Aggressive fertility treatments are not responsible for the

Question

Aggressive fertility treatments are not responsible for the rise in the incidence of twin births. Rather, this increase can be attributed to the fact that women are waiting longer to become mothers. Statistically, women over 35 are more likely to conceive twins, and these women now comprise a greater percentage of women giving birth than ever before.

The argument above is flawed in that it ignores the possibility that

a. many women over 35 who give birth to twins are not first-time mothers
b. women over 35 are not the only women who give birth to twins
c. the correlation between fertility treatments and the increased incidence of multiple births may be a coincidence
d. on average, women over 35 are no more likely to conceive identical twins than other women are
e. women over 35 are more likely to resort to the sorts of fertility treatments that tend to yield twin births.

E

If  "women over 35 are more likely to resort to the sorts of fertility treatments that tend to yield twin births" , then this explains why  "women over 35 are more likely to conceive twins,"  
Thus, the argument that fertility treatments  "are not responsible for the rise in the incidence of twin births"  is flawed

Using POE: A is irrelevant. B is a bit too general. C is not so relevant. D is not so precisely related to the conclusion. E stands out as the best answer.

Late but E.
Women over 35 might have undergone fertility treatment which increases the likelihood of having twins.

Could someone explain why A is not the correct answer... Because argument says women are waiting longer to become mothers while A weakens by saying that women over 35 who give twin birth are not first time mothers.

Chembeti · Answer

True....B is very close but can be eliminated with the following reasoning. Argument mentions two points that are possible: one - aggressive fertility methods; two- women age is equal to or more than 35. B touches the age point, but in a very vague way. E touches the fertility point in a very specific and direct way. Both B & E are possible but the possibility of E's possibility is high

Chembeti · Answer

A implies that those women over 35 had already given birth to single child. 
Once they give birth to one child and wait for the second pregnancy they are merely   "waiting to give birth"   but not   "waiting to become mothers"   which the author argues about.
