The following is a part of a written test (fill-in-the-blank questions).
Scientists believe that with global warming, we can expect more severe weather patterns, including heat waves, hurricanes, floods, and drought. The oceans may become more acid. Weather events like this can 1(have / increase) health risks, damage economies, destroy habitats, and affect our quality of life.
Changes in the Earth’s climate 2(have / increase) the potential to affect people’s health. For example, people can be hurt directly by extreme weather events caused by climate change, such as powerful hurricanes.
The test giver says that the right answer is:
(1- increase 2- have)
But isn’t
(1- have 2- increase)
impossible?
The tester is correct. The switch is not impossible, but it is less natural. #1 is for parallelism with the other predicates, which are dynamic verbs.

The tester is correct.
The switch is not impossible, but it is less natural. #1 is for parallelism with the other predicates, which are dynamic verbs.
#2 "have the potential" is a much better collocation. "Increase" means that the potential already exists, which is not a sound presupposition.
