- Purpose of physical sciences is to predict the order of events
- Human behavior can sometimes be predicted
- However, successful predictions of human behavior do not provide understanding of it.

a) This is part of the premise.

b) The argument expresses exactly the opposite.

c) Correct. The use of 'however' after the human behavior premise, indicates that in the physical sciences, ability to predict events does provide an understanding of it.

d) This is part of the premise.

e) This is never indicated or mentioned.

Little confused here... Option C says that in some cases, the understanding of the event comes through the ability to predict the occurrence of the event.
But how do you relate this to the stimulus which talks about the human behavior?? Can you explain as I am not able to correlate the reasoning behind bringing in the Physical sciences based on the human behavior info ??

Based on:
- Purpose of physical sciences is to predict the order of events
- Human behavior can sometimes be predicted
- However, successful predictions of human behavior do not provide understanding of it.

If:
A = in physical sciences the order of events can sometimes be predicted
B = human behavior can sometimes be predicted
C = successful predictions provide understanding of it

We can say:
(1) A
(2) B, however not C

The word 'however' indicates that C's relation to B is in contrast to C's relation to A, so:
(1) A, and C
(2) B, however not C

So you can see that in some cases (physical sciences) but not in others (human behavior), predicting the occurrence of an event leads to an understanding of an event.

The only thing that I'm making an assumption on, is that:
X leading to Y, is the same as Y consisting of X. (in this context)

This is the OE provided.
[Reveal] Spoiler:
“For” (line 5) is a synonym for “because,” and the
last clause is therefore the evidence for the second
clause, which (A) paraphrases. Notwithstanding our
occasional ability to predict human behavior, to do
so doesn’t mean that we understand it (conclusion)
because one needs to know the goal of human
behavior (evidence), something that the author
implies we can never know.
(B) contradicts the author. He explicitly states that
prediction can and does exist independent of
understanding of purpose.
(C)—the author never tells us what understanding
consists of (or “in,” in the test makers’ odd usage),
only what it requires. In other words, the author
provides a condition necessary for understanding
but not—as (C) suggests—the conditions sufficient
for it.
(D) reflects sentence 1, which mentions the
prediction of physical behavior in order to draw a
contrast with the prediction of human behavior
(from which the author proceeds to his true
interest, the understanding of human behavior).
(E)—“psychological states” is jargon, mumbo-jumbo
that doesn’t appear in the text and certainly
doesn’t amount to a paraphrase of “knowing a
human actor’s goal.”

Only reason I rejected A was because it seemed too simple to be correct.. and fell in the trap of C - an option which sounds correct but for a reason easily overlooked in the enthu to find correct option!
A lesson learnt
