Official Explanation:The administrators of a high school need to choose between two new science textbooks for their 10th graders. One of the books,
Science Now, costs considerably more, and is considered less in-depth, than the other book,
Science Stories. Despite this, the administrators have chosen to purchase
Science Now.
Which of the following, if true, most helps to explain why the school administrators chose to purchase Science Now rather than Science Stories? (A) Science Stories has fewer full-page illustrations than does Science Now.(B) The publishers of Science Now will lower the price of the book if a school has purchased other book titles that they have published.(C) Science Stories was published several years earlier than Science Now and contains outdated material and inaccuracies.(D) The publishers of Science Now also publish 11th and 12th grade material that is widely considered the best currently available.(E) For the past 10 years, the high school used science textbooks that were published by a company whose president is now president of the company that publishes Science Now.Question Type: Strengthen
Boil It Down: High school needs to choose a new science book.
Science Now is more expensive and less thorough than
Science Stories - but they’re choosing
Science Now anyway.
Goal: Find the option that best explains WHY the school is choosing Science Now over Science Stories. Analysis:This question is asking for evidence that would strengthen the administration’s conclusion. No evidence (premises) supporting this conclusion is provided.
Conclusion: Science Now is a better choice than is
Science Stories despite the higher price and less in-depth material.
To strengthen the conclusion, there must be a strong enough reason that
Science Now is the better choice. Choice C clearly states that
Science Stories is outdated and inaccurate. Those are two strong reasons to select the other book.
(A)
Science Stories has fewer full-page illustrations than does
Science Now.
This points out a difference between the two books, but does not provide a clear reason why one is a better choice. How important are the illustrations? It’s not clear. Perhaps the school would prefer that the book have fewer illustrations.(B) The publishers of
Science Now will lower the price of the book if a school has purchased other book titles that they have published.
This choice would only work if we knew that other books would be purchased AND if we knew that the price difference is sufficient to select Science Stories.(C)
Science Stories was published several years earlier than
Science Now and contains outdated material and inaccuracies.
This is the correct choice. It gives a clear reason why one book is preferable to the other. No more info is needed.(D) The publishers of
Science Now also publish 11th and 12th grade material that is widely considered the best currently available.
This doesn’t directly affect the choice to purchase the 10th grade book, and that’s all we care about. (E) For the past 10 years, the high school used science textbooks that were published by a company whose president is now president of the company that publishes
Science Now.
This doesn’t directly affect the choice to purchase the book. There are too many links that we would have to supply to make this choice work.Don’t study for the GMAT. Train for it.
