<p>This is a CB question...</p>
<p>The seven month old baby was considered precocious</p>
<p>(to her family) because she was (already able) to grasp
A<br>
tiny items (delicately) (between her thumb) and</p>
<p>forefinger. (No error)</p>
<p>I thought it was no error, but the answer is A, (to her family). Why?</p>
<p>Here’s another one…as you can see I failed the grammar section </p>
<p>Despite research (on the diagnosis of) heart disease and</p>
<p>the use of (increasingly) sophisticated technology</p>
<p>(in its treatment), the condition of coronary arteries (is)</p>
<p>still difficult to assess precisely. (No error)</p>
<p>The answer is E. But if you look closely you can see that the research is being performed on the “diagnosis of heart disease”. So “in its treatment” doesn’t seem right because “it” modifies the diagnosis and the technology is clearly not treating the diagnosis…</p>
<p>First one is by her family</p>
<p>IDK why I don’t know rules, but that is what it should be. You can tell if you sound it out.</p>
<p>Hmm…I guess I was overanalyzing the second one.</p>
<p>it’s by because the sentence is in the passive voice you need an agent that the action is performed on. The agent is always presented with “by …”</p>
<p>And for the second one…is blah… next person please lol i would’ve picked E on my last try since i can’t find anythign definitely wrong other than that it’s long (but not a run-on)</p>
<p>I think the main thing to take from the second one is that pronouns can refer back to a variety of things. Clearly, CB didn’t have a problem with it referring back to heart disease instead of diagnosis.</p>
<p>but see that’s what stumps me…sometimes there is an error if the pronoun doesn’t refer to a specific noun. but in this case there isn’t. Oh well, the best thing to do is hope that none of these weird type of questions show up on the real test.</p>
<p>that’s kind of true. Although you can only do treatment on heart disease… i’ve seen many questions where the pronoun was pretty clear if you knew how to read… and that was considered wrong.</p>
<p>the first one may be trying to confuse you because that how “seem” would behave.
the baby seemed precocious to her family
the baby was considered precocious to her family -> wrong</p>
