Which sentence states the central idea of the passage?

A

Explanation:

The whole passage talks about psychology and A gives the main idea. A tells you that psychology is the understanding of the human mind while the other answers tell you that psychology is a good career path. A is the only answer that explains what psychology is and psychology is the main idea of the passage.

type of error:

the error in the sentence is a "dangling modifier". a dangling modifier is a phrase, word or clause that "dangles" because there is not target to modify. in this case, "after mopping the floor" is the dangling modifier since it has no word to modify. the noun "house" cannot mop the floor; therefore there is a mistake in the writing of the sentence.

different strategies reach different people based on their ability to understand the material. (from personal experience) when writing an argumentative essay write explaining the subject as though your audience never heard of it before and it is just being introduced, then explain why other people hate it also, afterward you would explain why that would be wrong. i hope that : )
