Answer:
Step-by-step explanation:
The correct sentence is:
"Many of the considerations for implementing a program are similar to those for a coaching program or mentoring."
In this sentence, the subject is "many of the considerations," which is plural, so the correct verb form to use is "are." The sentence is comparing the considerations for implementing a program to the considerations for a coaching program or mentoring, so both coaching and mentoring are correct words to use in the sentence.
