Answer:
Q6. Hinduism, Q2. Correct, Q1. Correct, Q5. Correct.
Step-by-step explanation:
Q6. Predominant means the strongest/main, and nearly 80% of the population practices Hinduism in India, a little over 14% of the people practice Islam there.
Q2. Islam, Christianity, and Judaism are not polytheistic, they are monotheistic. I believe the ones you chose are correct.
Q1. I think those are correct as well.
Q5. I also think this one is correct since it was the spread of christianity rather than other religions; Apostle Paul is a missionary so that would make sense.
