In each question a statement is given, followed by two assumptions, numbered I and
II. An assumption is supposed or taken for granted. You have to consider the statement and assumptions and decide which of the assumptions is implicit in the statement. Statement: A group of scientists is deploying seed-dropping drones in deforested regions of the Amazon to accelerate the regrowth of native tree species. Assumptions:
I. Traditional methods of manual reforestation are not fast enough to counteract the current rate of deforestation in the Amazon.
II. Seeds dropped from drones are capable of germinating and growing into trees in these deforested environments.

The logic followed here is as follows: The statement describes the use of specialized technology (drones) to "accelerate" reforestation efforts in a specific area. Assumption I is implicit because the use of drones to "accelerate" the process implies that existing methods are insufficient or too slow to meet the current needs of the region. Assumption II is implicit because the act of deploying seeds via drones would be a futile experiment unless the scientists took it for granted that these seeds have a viable chance of growing in that specific environment. Since both the need for speed and the viability of the method are taken for granted in the scientists' plan, both I and II are implicit. Thus, C is the right answer.
