Question

goodall proved the theory wrong when she observed the chimps using pods as weapons. she also observed the chimps using twigs as a sort of fishing pole and spoon. they would dip twigs into termite mounds, in order to collect and eat the termites more easily. even more amazing, some chimps would break the twigs for the purpose of creating a more useful tool. scientists were flabbergasted: only humans were supposed to have the ability to be capable of tool - making, and they could not believe what goodall had accomplished.
what does flabbergasted most likely mean?
a. joyful
b. alarmed
c. shocked
d. concerned

Explanation:

To determine the meaning of "flabbergasted", we analyze the context. The text says scientists thought only humans could make tools, but Goodall observed chimps making tools. This unexpected discovery would make scientists feel shocked. "Joyful" (A) is positive emotion, not fitting. "Alarmed" (B) implies fear, not here. "Concerned" (D) is worry, not matching. "Shocked" (C) fits the surprise from the unexpected observation.

Answer:

C. shocked
