Question

what does the following sentence suggest?
gestational diabetes is a blood - sugar disorder that develops during pregnancy; pregnant women who have been diagnosed with the disease must avoid foods high in sugar.
all pregnant women must avoid foods high in sugar.
certain pregnant women must avoid foods high in sugar.

Explanation:

The sentence states that gestational diabetes (a blood - sugar disorder in pregnancy) means pregnant women with this diagnosis must avoid high - sugar foods. The option "Gestational diabetes is a blood - sugar disorder that develops during pregnancy; pregnant women who have been diagnosed with the disease must avoid foods high in sugar." directly reflects the meaning of the sentence. The other options either use "all" (which is too general as the original is about those diagnosed) or "certain" (which is not accurate as it's about those with the disease) instead of the specific group of pregnant women with gestational diabetes.

Answer:

Gestational diabetes is a blood - sugar disorder that develops during pregnancy; pregnant women who have been diagnosed with the disease must avoid foods high in sugar.
