Question

halley is 40 years old and she and her daughter clara, 20, are both currently pregnant. which statement with regard to these two mothers is most accurate?
a. halley has a greater risk of having a miscarriage.
b. claras odds of having a baby with down syndrome are three times higher than halleys.
c. clara has a greater risk of giving birth to a baby with sickle - cell anemia.
d. halley is twice as fertile as clara.

Explanation:

As a woman ages, the risk of miscarriage increases. Halley is 40, an older - age for pregnancy compared to Clara who is 20. The risk of chromosomal abnormalities and other pregnancy - related complications that can lead to miscarriage is higher in older women. Down syndrome risk is higher in older women (Halley), sickle - cell anemia is a genetic disorder not related to age of the mother in this context, and fertility generally decreases with age so Halley is not more fertile than Clara.

Answer:

A. Halley has a greater risk of having a miscarriage.
