In paragraph 2 of the passage, there is a missing sentence. The paragraph is repeated below and shows four letters (A, B, C, and D) that indicate where the following sentence could be added. *"These landscape features differ from runoff channels in a number of ways."* Where would the sentence best fit? Outflow channels are probably relics of catastrophic flooding on Mars long ago. (A) They appear only in equatorial regions and generally do not form extensive interconnected networks. (B) Instead, they are probably the paths taken by huge volumes of water draining from the southern highlands into the northern plains. (C) The onrushing water arising from these flash floods likely also formed the odd teardrop-shaped “islands” (resembling the miniature versions seen in the wet sand of our beaches at low tide) that have been found on the plains close to the ends of the outflow channels. (D) Judging from the width and depth of the channels, the flow rates must have been truly enormous—perhaps as much as a hundred times greater than the 105 tons per second carried by the great Amazon River. Flooding shaped the outflow channels approximately 3 billion years ago, about the same time as the northern volcanic plains formed. (A) Option A (B) Option B (C) Option C (D) Option D

Complete the summary by selecting the THREE answer choices that express the most important ideas in the passage. Some sentences do not belong in the summary because they express ideas that are not presented in the passage or are minor ideas in the passage. Write your answer choices in the spaces where they belong. You can either write the letter of your answer choice or you can copy the sentence. *"There is much debate concerning whether Mars once had water."* • • • Answer Choices: (A) Various types of images have been used to demonstrate that most of the Martian surface contains evidence of flowing water. (B)The runoff and outflow channels of Mars apparently carried a higher volume of water and formed more extensive networks than do Earth’s river systems. (C)Mars’ runoff and outflow channels are large-scale, distinctive features that suggest that large quantities of liquid water once flowed on Mars. (D)Although some researchers claim that Mars may once have had oceans, others dispute this, pointing to an absence of evidence or offering alternative interpretations of evidence. (E) While numerous gullies have been discovered on Mars since 2000, many astronomers dismiss them as evidence that Mars once had liquid water. (F) There is very little evidence of liquid water on Mars today, and it is assumed that all the water that once existed on the planet is frozen beneath its surface.
