Some of our social sciences P : that cannot be attacked by modern society Q : such as psychology and sociology R : seem o have become S : sacred cows The Proper sequence should be:

PQRS
QRSP
RSPQ
RSQP

The correct answer is: D. RSQP

The sentence is about how some social sciences, such as psychology and sociology, have become sacred cows that cannot be attacked by modern society. The correct sequence of the sentence is:

R: Some of our social sciences seem to have become sacred cows.
S: Sacred cows are things that cannot be criticized or attacked.
Q: Psychology and sociology are examples of social sciences.
P: Modern society cannot attack these social sciences.

The other options are incorrect because they do not follow the logical order of the sentence. For example, option A (PQRS) would mean that modern society cannot attack sacred cows, which is not the case. Option B (QRSP) would mean that psychology and sociology are sacred cows that cannot be attacked by modern society, which is also not the case. Option C (RSPQ) would mean that modern society cannot attack psychology and sociology, which is true, but it does not explain why this is the case.
