Answer Choice A is the correct answer because Lines 22-24 say, “Those deep HUDF images revealed some of the most distant galaxies ever found, which look very different than nearby galaxies.” These “most distant galaxies” refer to galaxies from billions of years ago, and these lines most clearly match Answer Choice A which says that galaxies from billions of years ago “looked very different from galaxies today.” Answer Choice B is incorrect because the Passage only mentions that Type Ia supernovae are a “valid yardstick for the early universe,” not that they dominated galaxies billions of years ago. Answer Choice C is incorrect because the Passage doesn’t tell us that galaxies from billions of years ago were grouped together in one location, and actually implies the opposite when it says that the HUDF “represented just a pinprick poke at the universe.” Answer Choice D is incorrect because the Passage doesn’t tell us that these early galaxies were larger than astronomers had expected.
How to solve this? The Question asks, “Based on the passage, what can reasonably be inferred about galaxies billions of years ago?” To solve this question, we should go back to the Passage and look for a Text that tells us about these old galaxies. Using the Question Order Rule, we can predict that our text is likely to come before Line 31. Lines 22-24 tell us [...].
