C is biased because the people were paid to evaluate the car. They are more likely to say better things about it than if they weren't paid.

I believe it is B. The meaning of bias is prejudice in favor or against someone or a group compared to another in an unfair way. Many can have a one sided opinion about something such as who is going to win the race. However, choosing different cheese is more of an opinion showing which they prefer more than being bias.

Answer:

See Explanation

Explanation:

What Adi failed to realize is that the oily substance that was obtained from lavender consists of a mixture of substances. It is not only the required fragrance that is present in the extract.

This experiment will not work because those other components in the mixture may be erroneously identified when they show up in the mass spectrum of the extract and may be mistaken for the fragrance in question.

Hence the experiment will not work because; if some kind of separation method is not used to identify other impurities in the oil, many other substances may be mistaken for the actual fragrance.
