What made it possible for some slaves to be able to buy their freedom? slaves began an underground trade in goods. some slave owners gave slaves an allowance. the increased demand for labor gave slaves more power. taxes were collected from slave owners to provide funds for slaves.

The answer is, 'some slave owners gave slaves an allowance'

While it was very rare, a few slaves owners gave their slaves allowance for doing work on their plantations, the allowance wasn't big and it often took years for slaves to buy their freedom.

the answer is b just took the test

so, based on the research i've done. the u.s. government were always on a wild goose chase just to take down castro. he then retired his trone to his brother raul in 2008 due to some health issues. so it's obvious your answer would be:

castro had no allies from which he could receive aid.

hope this and have a fantastic day!
