Dear SDCAR, thanks for your workI don't understand No.4,why not choose E?
4) Garbage in this neighborhood probably will not be collected until Thursday this week.(Main conclusion) Garbage is usually collected here on Wednesdays, and the garbage collectors in this city are extremely reliable.(is it an opinion or premises?i am not quiet sure)However, Monday was a public holiday, and after a public holiday that falls on a Monday, garbage throughout the city is supposed to be collected one day later than usual.

The
argument proceeds by

(A) treating several pieces of irrelevant evidence as though they provide support for the conclusion.
(B) indirectly establishing that one thing is likely to occur by directly ruling out all of the alternative possibilities
(C) providing information that allows application of a general rule to a specific case.
(D) generalizing about all actions of a certain kind on the basis of a description of one such action
(E) treating something that is probable as though it were inevitable

Main conclusion: Garbage in this neighborhood probably will not be collected until Thursday this week

And the whole passage sets up the logic chain which supports the above conclusion.  There is no somthing probable involved here. If . . . then ...  statements are clearcut, not probable, but inevitable if the trigger is present.

Hello,SDCAR
today i did some exercises.But i don't know how to do "Must be true".Can you give me some ideas?
And what is the difference between 'principle' and'back info'?

Principle is a theory, which is kind of abstract in words and meaning and which can help solve some practical or real problems.

Back info is similar to background information.

Must-be-true is the easiest among all problems, because the correct answer MUST be true according to the passage.  Anything which is not mentioned in or derived from the passage IS wrong.
