When talking about recycling, people don't seem to consider the recycling of clothing.
The comma should be placed between the first use of recycling and people. The subordinate clause is "when talking about recycling". This is a clause because of the word "when". When makes the reader wonder when what? The main clause is "people don't seem to consider the recycling of clothing."
The answer is C.
We’re talking about what changes can be made to keep players safe from head injuries
Answer A is incorrect because the time head injuries were first discovered is irrelevant to keeping kids safe.
Answer B is incorrect because you’re asking a yes or no question for a difficult and elaborate topic.
Answer D is incorrect because we’re currently examining why head injuries are dangerous and what can be done to prevent them.
Answer E is incorrect because this is just speaking of the faults of the human skull. This doesn’t help truly solve the changes that can be made.
I hope this helps!
