Explanation:

The word "expertise" means expert skill or knowledge in a particular field. The first two sentences use it in the context of having expert - level knowledge or skill in specific areas (generating press coverage and emerging technologies in engineering). The third sentence uses "expertise" wrongly as it should be a prediction or opinion, not the meaning of expertise. The fourth sentence uses it as if it means a problem or inconvenience, which is incorrect. The fifth sentence uses it as an adjective - like form instead of a noun, which is wrong.

Answer:

The campaign director has proven expertise in generating press coverage.
Their area of expertise in engineering is emerging technologies.
