Can you please tell me if the following alternatives are all possible? I hope you can have a look at them.

1)The jewish communities were restricted in their (or the) professions they could follow.
2)As Christians were not allowed to lend money at interest, many Jewish people made money through usury as moneylenders.
3)The Black Death was so called because the body went dark-coloured after death.
4)For my main course I'd like grilled chicken breast/a fried egg with asparagus/roast lamb with spinach and cauliflowers.
5) To drink I'll have a half-litre bottle of fizzy water and two glasses of orange juice.
6) The managere fired both of them (or them both?).You can find a clothes shop half way up (also down) the main street on the right-hand side.
7) What about going for a motorbike/bike ride uphill/for a walk in the city centre? I have to study for tomorrow's physics test/help my mum with the housework/go to the dentist.
