A) The survey was conducted with a representative sample of consumers who had used both Brand A and Brand B.
B) Brand B had recently launched a major advertising campaign to increase brand recognition.
C) Many of the participants who preferred Brand A had used it exclusively for several years.
D) The survey was conducted in an area where Brand A has a higher market share than Brand B.
E) A similar survey conducted last year found that 70% of participants preferred Brand A over Brand B.

Answer:

A) The survey was conducted with a representative sample of consumers who had used both Brand A and Brand B.

Explanation: This choice strengthens the argument because it provides evidence that the participants had a fair basis for their preferences, making the survey results more reliable. The other choices either provide additional context or do not directly address the reliability of the survey results.

can someone please explain this? as per the paragraph, the result of the survey mentions that people were not very familiar with product B which states that there was little basis for the choice. would this not make option 'D' the more appropriate choice?

thank you

I believe in this question we need to prove why the survey's result was accurate. The passage implied that participants didn't know much about product B.

So basically we need to find an answer that directly negates that implication (as all the info in the options are assumed to be correct).

This makes option A the only correct choice.

Hello Priya,

Here is my thought. Say per option D, 51% is the share of Brand A and the rest is B. The question stem also says that "  However, the same survey found that many respondents were unfamiliar with Brand B  ". In other words, we can say that they chose brand A over B as they are not familiar with B and 49% is a significant number to not to get unnoticed. That is the particular weakness in the option D as it strengthens but not "most". I hope this helps
