In the question below, a situation is given, followed by two statements that may or may not be concluded from the situation. Select the option that contains the conclusion(s) that follows. People's willingness to use a Zika vaccine will be influenced by how they weigh the risks associated with the disease and the vaccine, and by their misconceptions about other vaccines, a new study has found. 1. People will be willing to use the Zika vaccine if it is scientifically proven that the risk of contracting the disease is very minimal. 2. People will be willing to use the Zika vaccine if it is scientifically proven that the vaccine carries no or minimal risk and the disease is life-threatening.

The situation clearly talks about the fact that people would weigh the risks of the disease and the vaccine which would determine their willingness to use the vaccine, and it can be inferred from this that if the risks of the disease are more than those of the vaccine, then they would be willing to use it. This is depicted by 2, which tells us that disease carries high risks (it can cause death), and the vaccine is not very risky. Thus, (b) is the right answer. 1 will not follow as it talks about the risk of contracting the disease in the first place, whereas the given situation talks about the risk carried by disease itself (the adverse effects on health). Secondly, even if the risk of contraction were mentioned in the situation, it would make sense if the statement concluded that the willingness of people to use the vaccine was directly proportional to the risk of contracting the disease. 1 however, concludes the opposite.
