<p>And why 
?</p>
<ol>
<li><p>B
In A and C, the pronoun ‘it’ is incorrect since the two antecedents (illustrator and painter) require a plural pronoun.
In D, the pronoun ‘them’ has no clear antecedent.
In E, the “by… was how” construction is awkward.</p></li>
<li><p>D</p></li>
</ol>
<p>A comma can only used if correctly followed by an appropriate coordinating conjunction (and/or/nor/but/yet/so). Rule out A and C. Then rule out B because it contains the present tense verb ‘sets’ while the sentence refers to past accomplishments. E is simply awkward. Consider this: Alice introduced close-ups and double cars on fire by her setting cars on fire. It sounds wrong.</p>
<ol>
<li> B
The employees called in sick because they were getting nowhere by merely asking for a comprehensive health-care plan. The choice with “After” makes the logical implication clear. Because of their employer’s lack of response to their repeated requests, the employees called in sick. When you pull out the adverb and the second prepositional phrase from “because of repeatedly asking in vain” it becomes “because of asking,” which is not the reason that the employees called in sick. Admittedly, the use of “repeatedly” and “in vain” makes the meaning clearer, but the “After” clause is better. Choice C has the dreaded (by CB) comma splice. Choice D does not make the logical connection between the actions clear. The use of “while” in choice E does not fit the logical connection either. If you write “While A, B,” then you generally mean either B is happening at the same time as A, or “Even though A, B.”</li>

<li> A
Choice B has trouble with the verb. Is it “fought” or “took”? They are not connected properly. Choice C is wrong because after the semicolon, you need a complete clause (subject and verb). In that context, “fighting” does not count. The first part of the sentence says that Hingis caught up. The second part says that Williams regained the lead. You need a connector that emphasizes the contrast between the two parts. Neither “along with” nor “in fact” is a good choice for that.</li>
