A. Synthesize, if he is compiling multiple sources together.
ANSWER: I believe the answer is B, but I'm not sure.
a billion people, two-thirds of them women, will enter the 21st century unable to read a book or write their names,” warns UNICEF in a new report, “The State of the World’s Children 1999.”
UNICEF, the United Nations Children’s Fund, points out that the illiterate “live in more desperate poverty and poorer health” than those who can read and write. The shocking number — 1 billion people illiterate — generated frightening headlines in major newspapers.
Poverty in the poorest countries is indeed something that ought to concern all of us, especially in a season when we pause to remember the less fortunate. But as usual, there’s more to this striking statistic than UNICEF tells us. Consider three points.
The Good News. Bad news sells, news watchers tell us. And 1 billion people unable to read and write — about 16 percent of world population — is certainly bad news. But let’s deconstruct the news.
First, UNICEF’s actual number is 855 million, a figure that did not appear in major newspapers. That’s still a large number, but it is 15 percent less than 1 billion.
Answer:
The sentence with the best elements of parallelism of the examples provided is Option B. Science may be challenging, but it is also rewarding; reading might be time-consuming, but it is also enlightening.
Explanation:
Parallelism is a property of the way your sentences are structured in a piece of writing. It is usually a property that is particularly important when providing lists in something you write. All points on a list should start with a word in the same format, i.e. the listed elements should all start with a noun -- or a verb, if that is the case -- but not a mixture of those two elements. You see this mistake a lot on peoples resumes when they are listing things. Option B is best because "reading" is treated like the noun "science" in this case. Another example of the work "reading" being treated like a noun would be: "I have done the reading." Both sentences use the verb in the present progressive form in the second independent clause ending each sentence. That is another way they are parallel. There are other grammatical similarities that could be considered parallelsim in this example too!
