Question

.

Barbara McClintock won the Nobel Prize in 1983 when her ___ that genes in corn kernels could "jump" proved correct.
a. conjecture
b. discourse
c. interjection
d. precursor

Answer 1

Hi, the correct answer is A - conjecture. It is the only option that fits, because it means "an opinion or conclusion based on incomplete information". "Discourse" only means "communication", "interjection" is an exclamation, and a "precursor" is something that happens before something else.
