The paragraph is as follows:

"Initially, we constructed experiments that explored new relationships among six major systems of the human body: circulatory, digestive, muscular, nervous, reproductive, and respiratory. Then, we discovered, through a series of curious events and calculations, that these systems were all intricately involved in a kind of psychic economy. Our experimental research project has focused on what we call the Psycho-Physical Performance Scale. We believe that this work will revolutionize our understanding of human behavior. Therefore, we ultimately chose to classify different triggers of human actions and productions according to these new relationships."

Checking for spelling is a step in the proofreading process. Proofreading involves reviewing a written document for errors and making corrections as necessary. This can include checking for spelling errors, grammar mistakes, punctuation errors, and formatting issues.

The sentence that demonstrates proper subject-verb agreement is D. "Physics is a difficult subject to learn." In this sentence, the singular subject "Physics" agrees with the singular verb "is."

A dangling modifier is a phrase or clause that does not logically modify any word in the sentence. Example: "My brother had an old truck that sat by the garage that needed paint." The phrase "that needed paint" is a dangling modifier because it does not clearly modify any word in the sentence.

It is unclear whether it is the truck or the garage needed paint.

Proofreading is the final step, where you check for spelling and grammar mistakes. The other steps happen earlier in the writing process.
