Which claim is the narrowest and most focused? a. hydraulic fracturing is not as dangerous as people think, and natural gas is an important byproduct. b. zoos do not provide adequate habitats for elephants, nor do orangutans thrive in captivity. c. the government should cut welfare programs; homelessness among veterans is a major problem. d. schools should move away from standardized testing because tests often do more harm than good.

D.Schools should move away from standardized testing because tests often do more harm than good.

Explanation:

Claim D is focused on testing in schools and is, therefore, the narrowest of all.

Claim A seems to be focused on hydraulic fracturing and how harmless it is, yet it also mentions natural gas as an important byproduct.

Claim B is about inadequate zoo habitats for two different species of animals, so it cannot be considered the narrowest and most focused claim.

Claim C seems to be focused on cutting welfare programs, yet it also mentions the problem of homelessness among veterans. Not the narrowest claim either.  

the correct answer is a. how to make proposal that works.

indeed, the register is quite formal and the tone is especially objective as it avoids the use of the first and second person singular (i, you) and opts instead for the third person plural which is more impersonal and focuses on the data and the argument that is being developed by the author. the formality adds the impression of respectability to the work and the impersonality adds objectivity to it.

expository writing is one of the most common types of writing.
