<p>Here is how you might reword the sentence in your head:</p>
<p>“Oxytocin is the hormone that triggers uterine contractions during labor AND triggers the preliminary contractions known as Braxton Hicks.”</p>
<p>Basically, the verb “triggers” has two objects, “uterine contractions” and “the preliminary contractions.” You’re trying to replace it with a present active participle, “causing,” which is incorrect. Listen to how the sentence would sound with that alteration:</p>
<p>“Oxytocin is the hormone that triggers uterine contractions during labor, and causing preliminary…”</p>
<p>See the problem? The participle doesn’t work there.</p>
<p>I’m too tired to explain more accurately, so I hope this makes sense.</p>
<p>John walks the dog, walking as well the cat.</p>
<p>If you are unsure of the grammar rules, simplify (or rewrite) the sentence as you would a math expression. Remove all non essential clauses, prepositions, adjectives and adverbs that are there to fool your ear.</p>
<p>Of course, learning the grammar rules is the best course of action. This is just an ‘in case of emergency break glass’ strategy. </p>
<p>Oxytocin triggers <something>, as well as <something else=“”>.</something></something></p>
<p>vs.</p>
<p>Oxytocin triggers <something>, causing as well <something else=“”>.</something></something></p>
<p>I would add that the comma seems unnecessary in the original sentence. I don’t know what the rules say about that but since we didn’t get a non-comma choice I kept it in there…</p>

<p>Excellent advice for grammar and some of the math sections. Take it down to its bones, reduce the complicating words (complicated numbers) and test your response.</p>
<p>Sorry to bother you again but I’ve been doing grammar drill recently and i have a lot of questions.</p>

<li>The psychologist states that most people want the same things: interesting and meaningful work, respect, and to have them be loved for themselves alone.
(A) interesting and meaningful work, respect, and to have them be loved for themselves alone
(B) to have interesting and meaningful work, respect, and loved for themselves alone
(C) work that has interest and is meaningful, to have respect, and to be loved for themselves alone
(D) interesting and meaningful work, respect, and their own love
(E) to have interesting and meaningful work, to be respected, and to be loved for themselves alone

Why is E the right answer? I thought the psychologist was listing the things, so should them be nouns?
thank you!</li>

<p>i wonder if anyone can answer this one…“people who were familiar with the writer’s style were not surprised to find that he adopted a similar (style in his) articles.E”…i was confused between the fragment in the brackets and (no error)…i thought that it should be adopted for.</p>
