Choose two words from this group that are related. a. shout b.carefully c. create d. laugh

There are at least two ways to answer this question. This is because it is not clear exactly what it means for two words to “be related.”
First, you could say “create” and “carefully” are related. These are related because they could be used together. When a person creates something, he or she might do so carefully. Because you might create something carefully, the two words are, in a sense, related.
Second, you could say “laugh” and “shout” are related. I would say this is the better answer. These two words are related in two ways. They are related because they are both verbs. They are also related because they are both actions people can do with their own bodies. People can, without anything or anyone else, shout or laugh.
These are two options for this answer. I prefer the second option because those two words are connected to one another in two different ways.
