Keep the query in mind, when writing the entry
Any off-topic content, that does anything but directly answer the query, doesn't belong in that FAQ.
Say, the FAQ is How do I invest in US markets? Should I use a US broker, or India-domiciled mutual fund that invests in US markets? Which one's better option?
The answer to this query should focus on cost aspects of various options around investing in US markets.
Any discussion about investing in US markets, correlation with world markets, allocation in world indices etc. are off-topic, and doesn't belong in the FAQ itself.
Any single line that doesn't help a typical investor understand the problem / solution better, is not something that belongs in that FAQ. It might belong in a different series or article of its own, but not in that FAQ.
