Explanation:

1.

The statement is false. The decision for amniocentesis is often based on factors like maternal age, risk factors, and sometimes the woman's choice after consultation, not solely the physician's decision. But if we consider standard medical practice where the physician (along with patient) decides, maybe true? Wait, actually, the italicized word is "physician"—no, wait, the first statement: "The physician decides whether a woman will have amniocentesis." Actually, in reality, it's a shared decision, but maybe the answer here is + (true) if we take the context. Wait, no, maybe I'm overcomplicating. Wait, the first statement: let's check. Amniocentesis is a procedure, and the physician (with patient) decides. So maybe true. So +.

A miscarriage is a pregnancy loss before 20 weeks; after 20 weeks, it's called a stillbirth. So cross out "miscarriage" and write "stillbirth".

A mother's diet provides nutrients to the fetus, so it influences fetal development. So true, +.

Answer:

+
