Мой вариант с пояснениями:

1. Is his knowledge in History good?
   Knowledge — неисчисляемое, требует глагол в ед. числе. (Естественнее: knowledge of history.)

2. Where are your clothes?
   Clothes — существительное только во множественном числе → are.

3. Are his trousers on the chair?
   Trousers — парное существительное (как jeans, shorts) → множ. число.

4. Whose was that money?
   Money — неисчисляемое → ед. число (was).

5. He gave me some very good advice.
   Advice — неисчисляемое; множественного advices нет. Для «совет» можно: a piece of advice.

6. I don’t like the colour of your hair.
   Когда речь о волосах на голове в целом — hair неисчисляемое. Hairs — про отдельные волоски.

7. I never eat much bread.
   Bread — неисчисляемое; breads употребляется только про виды хлеба (редко: different breads).
