The correct answer is (E).
Here's a breakdown of the roles of the two boldfaced portions:
"The government has recently been severely criticized for its decision to block access to a few websites": This phrase describes the negative reaction or criticism that the government's action has received. It sets up the problem that the rest of the argument is responding to.
"while it believes in freedom of speech and expression, this was an emergency": This phrase is the government's defense. It acknowledges the principle behind the criticism (freedom of speech) but then provides the overriding reason—an "emergency"—as the justification for the necessity of its action.
It explains why the government felt compelled to act in a way that would otherwise be criticized.
Analysis of the other options:
(A) The second part is not an "action" taken in response; it's a verbal justification for a past action.
(B) While the second part is related to the argument's point of view, calling it the point of view is imprecise. It's more accurately the justification for that point of view. Option (E) is more precise.
(C) The second part doesn't directly "attack" the criticism. Instead, it justifies the government's action by citing exceptional circumstances.
(D) The second part is not the conclusion. The conclusion is the unstated idea that "the government's action was justified." The statement "this was an emergency" is a key premise or reason that supports this conclusion.
Bunuel
The government has recently been severely criticized for its decision to block access to a few websites on which malicious information and photographs were being posted. The government has responded to this criticism by stating that
while it believes in freedom of speech and expression, this was an emergency and in such situations, you have to cut off the source of the problem.
