Answer:
B. The approval of a vaccine helps the economy.
Explanation:
Coronavirus vaccines are highly desired worldwide and it is not surprising that the launch of these vaccines would stimulate the markets and bring benefits to economies, as they generate a perspective of normality and progress.
This is confirmed by the text above, which shows that the launch of vaccines has increased stocks and boosted the economy.
Which sentence uses an objective case pronoun as an indirect object?
I sent him an attachment that included photos of the picnic.
The indirect object him identifies to whom the action of the verb <u>sent</u> is performed.
<em>Wrong options:</em>
I e-mailed him yesterday.
(The direct object <em>him</em> is the receiver of action within this sentence: I emailed him).
He wrote back to Bob and I with an answer to our questions.
(I is not an objective case pronoun; it should be "He wrote back to Bob and <u>me</u>...")
So, once again, the answer is the 2nd sentence (I sent him an attachment that included photos of the picnic.)
