I did:

 

SELECT name,region FROM bbc WHERE region IN ((SELECT region FROM bbc WHERE name LIKE '%India%'), (SELECT region FROM bbc WHERE name LIKE '%Iran%'))

 

Was this really the correct query? It says it is, but it just feels like there's a more simplified way.

Ignore the above post please. I would like for anyone that can solve this problem to help me out if they can:

 

SELECT name,population,region FROM bbc b WHERE 25000000 > ALL(SELECT population FROM bbc x WHERE b.region=x.region)

 

Is currently what I have, for 3b:
