Explanation:

- Intensify: This means to increase in strength, magnitude, or intensity. When something intensifies, it becomes stronger or more extreme.

- *Eliminate*: This means to completely remove or get rid of something. It does not relate directly to increasing in strength or intensity.

- *Terminate*: This means to bring something to an end. Again, this doesn't match with the meaning of increasing intensity.

- Strengthen: This means to make something stronger or more forceful. It aligns well with the idea of intensifying something.

- *Destroy*: This means to damage something so severely that it no longer exists or can function. This is the opposite of strengthening or intensifying.
