Absolute values are always:
1. Positive
2. Negative
3. Even
4. Odd
What is 1
The correct answer is positive. Absolute value tells you how far a number is from zero, which will always be a positive number. Even and odd do not play a part in absolute values.
Which substance makes up the pads that provide support between the vertebrae?
1. Bone
2. Cartilage
3. Tendon
4. Fat
What is 2
The pads that support the vertebrae are made up of cartilage. Cartilage, a strong form of connective tissue, cushions and supports the joints. Cartilage also makes up the larynx and the outer ear. Bone is a form of connective tissue that comprises the better part of the skeleton. It includes both organic and inorganic substances. Tendons connect the muscles to other structures of the body, typically bones. Tendons can increase and decrease in length as the bones move. Fat is a combination of lipids; in humans, fat forms a layer beneath the skin and on the outside of the internal organs.
What is the topic?
1. The most important point being made by the author
2. Evidence and backing for the main point
3. A specific perspective on an issue that the author supports with evidence
4. The subject of a text
What is 4
The subject of a text is the topic. The most important point being made by the author is the main idea. The evidence and backing for the main point are the supporting details. And a specific perspective on an issue that the author supports with evidence is the thesis statement.
What is the name for any substance that stimulates the production of antibodies?
1. Collagen
2. Hemoglobin
3. Lymph
4. Antigen
What is 4
The name for a substance that stimulates the production of antibodies is an antigen. An antigen is any substance perceived by the immune system as dangerous. When the body senses an antigen, it produces an antibody. Collagen is one of the components of bone, tendon, and cartilage. It is a spongy protein that can be turned into gelatin by boiling. Hemoglobin is the part of red blood cells that carries oxygen. In order for the blood to carry enough oxygen to the cells of the body, there has to be a sufficient amount of hemoglobin. Lymph is a near-transparent fluid that performs a number of functions in the body: It removes bacteria from tissues, replaces lymphocytes in the blood, and moves fat away from the small intestine. Lymph contains white blood cells. As you can see, some of the questions in the vocabulary section will require technical knowledge.
Which of the following numerals is not a prime number?
1. 3
2. 6
3. 17
4. 41
What is 2
A prime number has only two whole integer divisors, 1 and itself. This is true of 3, 17, and 41. However 6 can be divided by 1, 2, 3, and 6. It is therefore not a prime number.
Within which part of the brain is sensory information interpreted?
1. Cerebrum
2. Hindbrain
3. Cerebellum
4. Medulla oblongata
What is 1
The cerebrum contains the parietal lobe, which is the part of the brain that interprets sensory information. The cerebrum is the largest part of the brain. The cerebrum is divided into two hemispheres, connected by a thin band of tissue called the corpus callosum. The cerebellum is positioned at the back of the head, between the brain stem and the cerebrum. It controls both voluntary and involuntary movements. The medulla oblongata forms the base of the brain. This part of the brain is responsible for blood flow and breathing, among other things. The hindbrain refers to a section of the brain including the medulla oblongata, pons, and cerebellum.
What does the setting impact in stories?
1. Chronological context

The setting impacts the plot and character motivations.
Select the word that means “water loving.”
1. Homologous
2. Hydrophilia
3. Dipsomaniac
4. Hydrated
What is 2
Hydrophilia means “water loving.” One could say that humans have a hydrophilic body, because our bodies crave constant infusions of water. The word homologous means “corresponding or having the same relative position or structure.” A dipsomaniac is a person who cannot resist alcoholic drinks. Dipsomania is a compulsion that must be treated with behavioral therapy or medications such as Antabuse, which causes a violent physical reaction to alcohol. The word hydrated means “full of water or sufficiently full of water.” Patients need to be hydrated, and medical workers need to be hydrated while they are performing their duties.
|-87 + 3| =
1. 90
2. -90
3. -84
4. 84
What is 4
The correct answer is 84. First, perform the operation inside the absolute value symbol. -87 + 3 = -84. Then, take the absolute value of -84, which gives you 84.
How much air does an adult inhale in an average breath?
1. 500 mL
2. 750 mL
3. 1000 mL
4. 1250 mL
What is 1
An adult inhales 500 mL of air in an average breath. Interestingly, humans can inhale about eight times as much air in a single breath as they do in an average breath. People tend to take a larger breath after making a larger exhalation. This is one reason that many breathing therapies, for instance those incorporated into yoga practice, focus on making a complete exhalation. The process of respiration is managed by the autonomic nervous system. The body requires a constant replenishing of oxygen, so even brief interruptions in respiration can be damaging or fatal.
Two roads diverged in a yellow wood,
And sorry I could not travel both
And be one traveler, long I stood
And looked down one as far as I could
To where it bent in the undergrowth;
Then took the other, as just as fair,
And having perhaps the better claim,
Because it was grassy and wanted wear;
Though as for that the passing there
Had worn them really about the same,
And both that morning equally lay
In leaves no step had trodden black.
Oh, I kept the first for another day!
Yet knowing how way leads on to way,
I doubted if I should ever come back.
I shall be telling this with a sigh
Somewhere ages and ages hence:
Two roads diverged in a wood, and I—
I took the one less traveled by,
And that has made all the difference.
Robert Frost, “The Road Not Taken"
Which option best expresses the symbolic meaning of the “road” and the overall theme?
1. A divergent spot where the traveler had to choose the correct path to his destination
2. A choice between good and evil that the traveler needs to make
3. The traveler’s struggle between his lost love and his future prospects
4. Life’s journey and the choices with which humans are faced
What is 4
Choice 4 correctly summarizes Frost’s theme of life’s journey and the choices one makes. While Choice 1 can be seen as an interpretation, it is a literal one and is incorrect. Literal is not symbolic. Choice 2 presents the idea of good and evil as a theme, and the poem does not specify this struggle for the traveler. Choice 3 is a similarly incorrect answer. Love is not the theme.
Select the meaning of the underlined word in this sentence:
The occluded artery posed a significant threat to the long-term health of the patient.
1. Closed
2. Deformed
3. Enlarged
4. Engorged
What is 1
The closest meaning for the word occluded as it is used in this sentence is “closed.” Occluded means “blocked or obstructed.” The word is commonly used to describe arteries that no longer allow the passage of blood. The word deformed means “misshapen or out of the normal shape.” Any deformed body part is a cause for concern. The word engorged means “overfull, especially of blood or food.” The organs of the body may become engorged when they are infected or diseased. Enlarged means “made larger.”
Is 45,064 divisible by 8? Explain why.
1. Yes, because it is even.
2. Yes, because the number formed by the last three digits is divisible by 8.
3. Yes, because it begins with an even digit.
4. No, because the last two digits form an even number.
What is 2
A number is divisible by 8 if the number formed by the last three digits is divisible by 8. In this case, the number formed by the last three digits (064) is 64, which is divisible by 8. This means that 45,064 is also divisible by 8.
Where is the parathyroid gland located?
1. Neck
2. Back
3. Side
4. Brain
What is 1
The parathyroid gland is located in the neck, directly behind the thyroid gland. It is the part of the endocrine system responsible for the metabolism of calcium. When the supply of calcium in blood diminishes to unhealthy levels, the parathyroid gland motivates the secretion of a hormone that encourages the bones to release calcium into the bloodstream. The parathyroid gland also regulates the amount of phosphate in the blood by stimulating the excretion of phosphates in the urine.
“His pride,” said Miss Lucas, “does not offend me so much as pride often does, because there is an excuse for it. One cannot wonder that so very fine a young man, with family, fortune, everything in his favour, should think highly of himself. If I may so express it, he has a right to be proud.”
“That is very true,” replied Elizabeth, “and I could easily forgive his pride, if he had not mortified mine.”
“Pride,” observed Mary, who piqued herself upon the solidity of her reflections, “is a very common failing I believe. By all that I have ever read, I am convinced that it is very common indeed, that human nature is particularly prone to it, and that there are very few of us who do not cherish a feeling of self-complacency on the score of some quality or other, real or imaginary. Vanity and pride are different things, though the words are often used synonymously. A person may be proud without being vain. Pride relates more to our opinion of ourselves, vanity to what we would have others think of us.”
Which sentence best states the theme of this passage?
1. Pride and vanity are offensive.
2. Fame and fortune can make a person proud.
3. Every person is proud in one way or another.
4. Pride can bring you fortune.
What is 3
A theme is a message or lesson conveyed by a written text. The message is usually about life, society, or human nature. This particular excerpt is exploring pride as it relates to human nature. Mary’s observations on pride are the best summary of the theme of this passage. “By all that I have ever read, I am convinced that it is very common indeed, that human nature is particularly prone to it.” The best answer choice is (3). Choice 1is contradicted in the first sentence. Choice 2 is discussed but is not the main theme. Choice 4 is not mentioned in the passage.
What is the best description for the word potent?
1. Frantic
2. Determined
3. Feverish
4. Powerful
What is 4
The best definition for the word potent is “powerful.” A strong drug may be referred to as potent. The ability of a man to reproduce is sometimes referred to as his potency. The word frantic means “frenzied or anxious.” A medical worker should never be frantic when dealing with patients and should do his or her best to keep patients from becoming frantic. The word determined means “set on a particular path.” Whenever possible, a health-care worker should try to ensure that patients are determined to take the necessary steps toward recovery and good health. The word feverish can mean either “having a high temperature” or “being worried and anxious.” A feverish patient should be comforted and given plenty of fluids.
Karen goes to the grocery store with $40. She buys a carton of milk for $1.85, a loaf of bread for $3.20, and a bunch of bananas for $3.05. How much money does she have left?
1. $30.95
2. $31.90
3. $32.10
4. $34.95
What is 2
The answer is $31.90. To solve this problem, you must know how to solve word problems involving decimal subtraction. In this scenario, Karen starts out with a certain amount of money and spends some of it on groceries. To calculate how much money she has left, simply subtract the money spent from the original figure: 40 - 1.85 - 3.20 - 3.05 . There is no reason to include the dollar sign in your calculations, so long as you remember that it exists. You cannot subtract the costs of these items at the same time, so you must either subtract them one by one or add them up and subtract the sum from 40. Either way will generate the right answer.
Which type of cholesterol is considered to be the best for health?
1. LDL
2. HDL
3. VLDL
4. VHDL
What is 2
High-density lipoproteins (HDL) are considered to be the healthiest form of cholesterol. This type of cholesterol actually reduces the risk of heart disease. A lipoprotein is composed of both lipid and protein. These substances cannot move through the bloodstream by themselves; they must be carried along by some other substance. Although most people think of cholesterol as an unhealthy substance, it helps to maintain cell walls and produce hormones. Cholesterol is also important in the production of vitamin D and the bile acids that aid digestion. The other answer choices are low-density lipoproteins (LDL), very-low-density lipoproteins (VLDL), and very-high-density lipoproteins (VHDL).
Read the statement or passage and then choose the best answer to the question. Answer the question based on what is stated or implied in the statement or passage.
Those so-called green fuels may not be as environmentally friendly as once thought. For example, producing natural gas is a much more labor-intensive process than producing an equal amount of conventional gasoline. Also, producing natural gas involves burning fossil fuels. Transporting natural gas also involves burning fossil fuels.
A weakness of green fuels is that
1. they are not as abundant as conventional fuel.
2. they require a lot more work to produce.
3. burning them releases fossil fuels.
4. they must be transported greater distances.
What is 2
Many green fuels require more work to produce than conventional fuels. The passage states, “producing natural gas is a much more labor-intensive process than producing an equal amount of conventional gasoline. Also, producing natural gas also involves burning fossil fuels.” There is no evidence to support answer choices 1 and 4. Answer choice 3 looks promising, but the passage does not mention that burning the green fuels produces fossil fuels, but rather that producing and transporting them uses fossil fuels.
Select the meaning of the underlined word in this sentence:
The doctors were less concerned with Bill’s respiration than with the precipitous rise in his blood pressure.
1. Detached
2. Sordid
3. Encompassed
4. Steep
What is 4
The word precipitous as it is used this sentence means “steep.” Doctors will often refer to a precipitous change in blood pressure. In general, precipitous changes are dangerous to a patient’s health. The word detached means “unconnected or aloof.” A common example is a detached retina, a condition in which part of the eye becomes disconnected and vision is damaged. The word sordid means “dirty” or “vile.” The word encompassed means “surrounded or entirely contained within.” For instance, a doctor might describe a treatment protocol as encompassing all aspects of the patient’s life.
