I think it is D. it makes the most sence.
Hi there!
The best possible scenario for the giraffes with longer necks to survive would be one in which all the lower leaves somehow disappear! This would mean only giraffes with longer necks can eat therefore those will have a better chance of surviving. Luckily the answer that fits that perfectly would be...
D. Monkeys swarm in and tear off all of the lower leaves to use for shelters.
for question 1.) i am pretty sure of answer a.)
for question 2.) the answer is most likely b.)
i would recommend waiting for a second opinion. just to be safe.
