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.
The answer to your question is either drawbridge or scaffolding. I want to go with drawbridge because it has support and stands of for itself, so its similar to a stucture if that makes sense.
Answer:
O C. The population's growth rate is increasing exponentially
I think the answer you’re looking for is
D. Carbon, hydrogen, and oxygen
-I hope this helps! Enjoy the rest of your day
