Studying relates to school and the negativity surrounding the topic. Most students do not enjoy going to school and since studying is mainly done for school it ends up having a negative correlation. It is also tiring because it is just repeating and memorizing information you already know. Learning on the other had you can do in and out of school. You can learn about things you enjoy and interest you which helps build a positive correlation with the topic. When you learn you are also taking in new information instead of repeating the same concepts over and over to memorize them.
Hope this helped! :))
The correct answer is A. use a singular verb.
If a noun is singular, but also collective, it means that it has the form of a singular noun, but refers to more than one entity. However, based on the context, it will either take a singular, or a plural verb.
For example: <em>The team is quite good</em> (where the team is a collective noun referring to all members together) VS. <em>The team are not behaving properly</em> (where this refers to all members individually).
Answer:
the last one seems most plausible
