Explanation

4. Given the information in the passage, the author can most reasonably be said to use which one of the following principles to refute the advocates’ claim that computer conferences can function as communities (line 15)?

Explanation

The stem cites line 15, but since the “refutation of the claim” doesn’t occur until paragraph 3, that’s where we must go. As we said before, ultimately the conference-as-community argument fails because computer conferences lack the kind of “genuine diversity” (line 58) that tie people together in “a sense of interdependence” (a phrase from line 4 that’s echoed in Paragraph 3). (E) correctly cites that diversity as a necessary condition of community.

(A) can’t be “refuting” the claim of conference-as-community, because (A) sums up why advocates make that claim in the first place (lines 36-41).

The adoption of etiquette conventions (B) is a characteristic of computer conferences that make them more respectful and supportive, but the author never asserts that, for instance, actual neighbors living next door have to have such etiquette conventions. They already are a community, because they live nearby and have mutual interests.

(C) is tricky. Proximity is listed in paragraph 1 as an aspect of “traditional communities.” But the question has to do with how the author refutes a claim, and the two necessary conditions of community in that refutation are a lack of discrimination (lines 44-47) and the presence of diversity (lines 47-59), and (C) mentions none of that.

(D) is easier to reject, since it’s a 180; diversity, not sameness, is what characterizes community.

Answer: E

Can someone explain why E, and not C, is the answer for question 4?

It's pretty dang tricky.

When you struggle with an RC passage, you need to check carefully these three things:

1). Have I misread/misinterpreted/misunderstood/missed detail in the passage or in the question itself?

2). Have I set a good prediction/goal for the right answer of that question to achieve?

3). Have I chosen an answer that matches a good prediction/goal for this question?

It seems most likely to me your struggles come from #1 here, particularly regarding the *question itself*.

What, *exactly*, does this question ask for?

Explanation

2. Based on the passage, the author would be LEAST likely to consider which one of the following a community?

Explanation

The four wrong choices all demonstrate elements that are a part of the author’s definition of community: shared interest (line 49)—note that the four wrong ones all use the words “the same”—as well as “genuine diversity” (lines 55-59). But in (C), there’s a sameness of interest with little diversity. Indeed, (C) could have been written as a clear illustration of conferences as described in lines 53-55.

Answer: C

1. Which one of the following most accurately expresses the central idea of the passage?

Which one of the following most accurately expresses the central idea of the passage?

The passage first explains why some people think computer conferences can function like communities: participants share interests, follow etiquette, and sometimes give emotional support. But the author argues that computer conferences still fall short of real communities because they are self-selected and less diverse. The central point is that computer conferences may offer some community-like benefits, but they are not true substitutes for actual communities.

(A) Because computer conferences attract participants who share common interests and rely on a number of mutually acceptable conventions for communicating with one another, such conferences can substitute effectively for certain interactions that have become rarer within actual communities.

This reflects the advocates’ view, not the author’s central view. The author argues that computer conferences do not fully substitute for actual communities.

(B) Since increased participation in computer conferences threatens to replace actual communities, members of actual communities are returning to the traditional interactions that distinguish towns or neighborhoods.

This is not supported. The passage does not say people are returning to traditional community interactions.

(C) Because participants in computer conferences are geographically separated and communicate only by typing, their interactions cannot be as mutually respectful and supportive as are the kinds of interactions that have become rarer within actual communities.

This is incorrect. The passage says computer conferences can be respectful and supportive.

(D) Although computer conferences offer some of the same benefits that actual communities do, the significant lack of diversity among conference participants makes such conferences unlike actual communities.

This is correct. The author accepts that conferences can provide respect, support, and shared interests, but argues that they are unlike actual communities because participants are self-selected and less diverse.

(E) Even if access to computer technology is broad enough to attract a more diverse group of people to participate in computer conferences, such conferences will not be acceptable substitutes for actual communities.

This is too speculative. The passage says current conferences lack diversity and access is limited, but it does not mainly argue about what would happen even if access became broader.

Answer: (D)

Hi ajit05052002,

Good question, because (A) is the classic "looks familiar" trap on a main-idea question. It sounds right because you did read those exact ideas in the passage - but they belong to the advocates, not to the author.

What (A) actually says

Read the end of (A): computer conferences "can substitute effectively for certain interactions that have become rarer within actual communities." That is precisely the advocates' claim from paragraph 1 (lines 11-16). The author sets that view up only to knock it down. So (A) captures the position the passage argues against - it can't be the central idea.

Why the whole passage points to (D)

Walk the three paragraphs and notice the author's own voice only arrives at the end:

- Para 1 - advocates say conferences can substitute for communities.
- Para 2 - develops their supporting characteristics (shared interests, etiquette, support in crises).
- Para 3 - the author finally speaks: "But... they nonetheless fall short of communities," the key reason being the "significant lack of diversity" (lines 55-59).

A correct main-idea answer must cover all three paragraphs, and especially the author's turn in para 3. (D) does exactly that: it concedes conferences "offer some of the same benefits" (the para 2 material) and states the author's actual point - the lack of diversity makes them "unlike actual communities."

The habit to lock in

On main-idea questions, always ask: whose view is this - the author's, or a view the author is setting up to challenge? An answer that restates the position the passage rejects (like A here) is never the main idea, no matter how much of its wording you recognize from the text.

So (D) wins because it matches the author's conclusion; (A) loses because it's the claim the author spends paragraph 3 refuting.

Answer: D
