Like a number of other articles, Ian Raghnalls article relied on a recent survey in which over half the couples applying for divorces listed money as a major problem in their marriages. Raghnalls conclusion from the survey data is that financial problems are the major problem in marriages and an important factor contributing to high divorce rate. Yet couples often express other types of marital frustrations in financial terms. Despite appearances, the survey data do not establish that financial problems are the major problem in contemporary marriages.

Which one of the following sentences best expresses the main point of the passage?

(A) Financial problems are not an important factor contributing to the divorce rate.

(B) Marital problems are more easily solved by marriage counselors than by married couples on their own.

(C) The conclusion drawn in Raghnall’s article is inadequately justified.

(D) Over half the couples applying for divorces listed money as a major problem in their marriages.

(E) Many articles wrongly claim that financial problems are the major factor contributing to the divorce rate.

Was stuck between option C and E. I found the line "Like a number of other articles, Ian Raghnalls article relied on a recent survey in which over half the couples applying for divorces listed money as a major problem in their marriages." a bit confusing. Could not decipher if the the line indicates that
other articles (like Ian's) relied on surveys OR - (1)
that other articles relied on surveys in which over half the couples applying for divorces listed money as a major problem in their marriages-(2)

If (1) i would choose C. If (2) i would choose E

I anyway just guessed the answer to be option C.
