○ genes from one species are inserted into a second species.
○ the goal of this process is to introduce a desired trait or characteristic into the second species.

Explanation:

The paragraph discusses the process of genetic modification. It explains that genes from one species are inserted into another to introduce a desired trait. For example, genes from bacteria are inserted into corn to make it resistant to pests. The overall goal of this process is clearly stated in the first - mentioned option.

Answer:

The goal of this process is to introduce a desired trait or characteristic into the second species.
