Please explain why each answer is either right/wrong and why. Thanks.

When the rate of inflation exceeds the rate of return on the most profitable investment avaliable, the difference between those two rates will be the percentage by which, at a minimum, the value of any investment will decline. If in such a circumstance the value of a particular investment declines by more than that percentage, it must be true that ________ .

Which one of the following logically completes the argument?

(A) the rate of inflation has risen

(B) the investment in question is becoming less profitable

(C) the investment in question is less profitable than the most profitable investment avaliable

(D) the rate of return on the most profitable investment avaliable has declined

(E) there has been a change in which particular investment happens to be the most profitable avaliable

**THIS IS A MATH PROBLEM!!**"When the rate of inflation exceeds the rate of return on the most profitable investment avaliable, the difference between those two rates will be the percentage by which, at a minimum, the value of any investment will decline."

=: Math here: RI(3%)-RR(2%)=1%(ID)----Premise 1

"If in such a circumstance the value of a particular investment declines by more than that percentage, it must be true that ________ ."

=the declined value of a particular investment >1%: Premise 2

= RI(3%)-RR(1%)=2%:

here small return but more inflate than P1)

Then the value of the particular investment is profitable than the most profitable investment? NO.
