Hello @farnoushsalimian,

The stimulus gives us the average usage of positive words at different points in the day. Positive word usage is common in the morning, decreases gradually in the afternoon, and increases sharply in the evening.

Based on these averages, the conclusion claims to track the mood of a typical person throughout the day. What is the problem with this?

I was able to eliminate A and D pretty quickly, leaving me with B, C, and E. Let's discuss those answer choices.

B. At first glance this seems like a reasonable criticism. However, the fact that "many" people do not use these positive words would not have an effect on the given averages. We still have the same trends throughout the day that the argument is based upon.

C. Are other methods of communication a better indicator of the typical person's mood than social media? We do not know, so we cannot say that C is a problem. There is no reason why word use in social media would have to correlate with word use in other communication forms.

E. This is saying that the people using positive language in the evening are usually not the same people using positive language in the morning. This tells us that, although the averages may be valid, they do not represent the mood shifts of a particular person. We cannot conclude that the typical person wakes up happy, becomes sad in the afternoon, and then feels better in the evening. What if some are morning people and others are night owls? This is the alternative explanation that E suggests.
