Question:
Read the arguments given below and answer the question that follows.
A number of independent studies have confirmed that XYZ minivans on an average have a better system of brakes as compared to any other minivans. Therefore, anyone wanting to buy a minivan solely on the basis of safety should buy XYZ minivans.
Which of the following most weakens the above conclusion?

Which of the following most weakens the above conclusion?
Show Hint
Look for an option that introduces a different safety measure where XYZ minivans do not perform as well.

- Independent studies have strong research methods which project reliable findings.
- EFG minivans have also fared better than ABC minivans on safety tests.
- In some studies ABC minivans gave better results in the brake tests.
- ABC minivans performed better than XYZ minivans in the frontal crash tests.

The Correct Option is D
Solution and Explanation
Step 1: Read the conclusion carefully.
The passage says that independent studies show XYZ minivans have better brakes than other minivans on average. Based on this single fact, the author concludes that anyone buying a minivan only for safety reasons should buy an XYZ minivan.
Step 2: Find the hidden assumption.
The conclusion assumes that brake quality alone decides how safe a minivan is. If some other safety factor shows XYZ minivans do worse than a rival, the recommendation to buy XYZ purely for safety becomes shaky.
Step 3: Test each option against this assumption.
Option (a) says the studies use strong methods and give reliable findings. This supports the conclusion instead of weakening it, so it is out.
Option (b) says EFG minivans beat ABC minivans on safety tests. ABC is not even the vehicle being compared to XYZ in the conclusion, so this does not touch the argument.
Option (c) says ABC minivans did better in some brake tests. This only questions how consistent the brake data is, it does not attack the idea that brakes equal overall safety.
Option (d) says ABC minivans beat XYZ minivans in frontal crash tests, which is a different and important safety measure. This shows that XYZ is not the safest choice overall, even though its brakes are good.
Step 4: Pick the strongest weakener.
Only option (d) attacks the real gap in the argument, the assumption that brakes are the only thing that matters for safety. It introduces another safety measure where XYZ actually loses out.
Final Answer:
Option (d) most weakens the conclusion because it shows XYZ minivans are not the overall safest choice, only the ones with the best average brakes.

- Read the passage and then determine the best choice for an answer from the questions given below. Base your choice on what this passage states directly or implies, not on any information you may have got from else where.
"The emancipation of women", James Joyce told one of his friends, "has caused the greatest revolution in our time."
Other modernists agree: Virginia Woolf, claiming that in a about 1910 "human character changed" and illustrating the new balance between the sexes, urged, "Read the 'Agamemon' and see whether your sympathies are not almost entirely with Clytemnestra". D.H. Lawrence wrote "perhaps the deepest fight for 200 years and more has been the fight for women's independence".
But if modernist writers considered women's revolt against men's domination as one of their "greatest" and "deepest" themes, only recently, perhaps in the past 15 years has literary criticism begun to catch up with it. Not that the images of sexual antagonism that abound in modern literature have gone unremarked - far from it. We are able to see in literary works the perspective we bring to them and now that women are enough to make a difference in reforming canons and interpreting literature, the landscapes of literary history and the features of individual books have begun to change. - Choose the correct sentence
