Answer 1

Hint: Here, we will analyse each option and compare it with the context of the given statement. After analysing we will choose the option which will be the conclusion of the statement given in the question.

Complete step-by-step answer:
We need to choose the best conclusion inferred from the statement “7 out of 8 veterinarians recommend Royal Rat rations for your fancy rat.”
This means that 7 out of every 8 veterinarians recommend Royal Rat Rations for a fancy rat.
However, this does not necessarily mean that it provides the best nutrition.
Thus, option (a) is not the best conclusion.
Also, not feeding a rat Royal Rat Rations does not mean the rat will be unhealthy. There are other rat rations for keeping the rats healthy.
Thus, option (b) is not the best conclusion.
The statement means that 1 out of the 8 surveyed veterinarians does not recommend Royal Rat rations for a fancy rat.
This does not mean that only one veterinarian in the world does not recommend it.
Thus, option (c) is not the best conclusion.
The statement means that 7 out of the 8 surveyed veterinarians recommended Royal Rat rations for a fancy rat. 7 out of 8 shows that a majority of the surveyed veterinarians recommend it.
Thus, option (d) is the best conclusion.
Therefore, the correct answer is option (d).

Note: Here we need to read the given statement and the conclusion very carefully. We need to understand which option is in the context with the given statement A common mistake we can make is to not read the options and answer that if 7 out of 8 veterinarians recommend it, thus only 1 veterinarian does not recommend it, and mark option (c) as correct. This is incorrect since option (d) is a better conclusion than option (c).
