During World War II, many factories that had produced household goods shifted to military production. Women entered industrial jobs in large numbers as labor needs grew. When the war ended, many women left these positions, but the experience challenged earlier assumptions about the types of work women could perform and influenced later changes in the workforce.
How does the ending refine the central idea?
A. It explains that women stopped working after World War II.
B. It broadens the passage from describing wartime employment to showing its longer-term effect on attitudes about women’s work.
C. It shifts the passage from factories to military strategy.
D. It argues that factory employment was easy for women.

Cheerleading routines require athletes to coordinate timing, strength, balance, and communication. During stunts, each athlete has a specific responsibility, and a missed count or unclear signal can affect the entire group.

A. Cheerleading requires coordination and communication among athletes.
B. Each athlete has a specific responsibility during a stunt.
C. Teams practice skills and safety procedures to improve performance and trust.
D. A missed count can sometimes affect a routine.

At first, short-form video platforms were used mainly for entertainment. Over time, teachers, museums, scientists, and news organizations began posting brief educational explanations. This made information easier to encounter, but it also created a challenge: short videos can leave out important context. Some educators now teach students to treat such videos as starting points and verify important claims with fuller sources.

D. The passage argues that teachers are responsible for controlling what students watch online.
What is C,The passage moves from the expanding educational use of short videos to the need for viewers to evaluate and verify the information they receive?
A school’s anti-bullying campaign originally focused on posters reminding students to be kind. Surveys later showed that many students knew bullying was wrong but were unsure what to do when they witnessed it. The school added lessons on reporting, safe intervention, and supporting targeted classmates. Later surveys showed that more students could identify specific actions to take.
Which evaluation BEST identifies what should be included in an objective summary?
A. Include the poster campaign because posters were the most visible part of the program.
B. Include the shift from general awareness to teaching specific actions because it shows how the school improved its response to the problem.

D. Exclude the later lessons because they occurred after the original campaign.
What is B, Include the shift from general awareness to teaching specific actions because it shows how the school improved its response to the problem?
A school introduced a rule requiring students to place phones in classroom storage pockets during instruction. At first, many students objected, saying they used their phones for school-related tasks. Teachers then increased access to classroom devices when technology was needed. After several weeks, teachers reported fewer interruptions, while students still had access to approved technology for assignments. The school kept the policy but continued reviewing student and teacher feedback.
Which summary BEST communicates the central idea and its development objectively?
A. The school unfairly restricted phones, but students eventually learned to accept the rule.
B. The school created a phone-storage policy, addressed concerns by providing other technology, and continued the policy after teachers reported fewer interruptions while students retained access to devices for academic work.
C. Students complained about the phone policy because they wanted to continue using social media during class.
D. Teachers preferred classroom devices to phones, so the school permanently banned phones from the building.
What is B, The school created a phone-storage policy, addressed concerns by providing other technology, and continued the policy after teachers reported fewer interruptions while students retained access to devices for academic work?
