Answer:
Cause: human
Solution: evolution
The hunters chose to harvest the sheep with the larger horns. Only smaller horned sheep survived and reproduced, so, over time the population had smaller horn size.
Explanation:
The trophy hunting (the bigger the better) on bighorn sheep has caused artificial evolution. The human selection (and killing) of sheep with large horns has led to the survival of sheep with smaller horns. It is a form of <em>artificial evolution </em>because in <em>natural evolution </em>bigger horns means to be better armed.
The third option is correct: Ronald Reagan's plan to outspend the Soviet Union led to a collapse of the Soviet economy and the political overthrow of its government.
