Presently, the biggest threat to biodiversity is;

Instead of riding his bike, a college student drives to class every day. He also drives to the store, to friend's houses, and everywhere else. every time he fills up his tank, a little bit of gasoline drips to the ground. The car's exhaust contains nitrogen oxides, which contribute to nitrogen levels in nearby water bodies.

Unique populations of giant tortoises live in the Galapagos Islands. This is the same group of islands where Darwin studied his famous finches. It is thought that the original ancestors of today’s giant tortoises came from the mainland of South America. These animals left and drifted in the ocean to the islands where they began to live, reproduce, and evolve. Each of the islands has a different habitat. Each species varies in shell shape and body structure. Information about two of these species of giant tortoises and their habitats is found in the table below.
When the saddle-backed tortoises extend their long necks out of the shell, they are unprotected from attack. Scientists hypothesize that during the evolution of this tortoise, they had few predators. Which statement best supports this hypothesis?
Competition between the predators and the tortoises would have resulted in a greater number of long necked tortoises.
The number of predators was greater than the number of tortoises.
Saddle-backed tortoises were not a part of the food chain.
Predators would have killed the tortoises with long necks, leaving more tortoises with shorter necks.
