Всем доброго времени суток! Пытаюсь разобраться с пассивным залогом, но не до конца понимаю, какое время нужно использовать.

Дано первое предложение. Используя слова в скобочках и пассивный залог, нужно составить второе предложение. Вроде сделал, но не уверен в правильности решения. Помогите, пожалуйста.

1 That's a beautiful picture. - Yes. It is painted by my mother.(It / paint / my mother) //или WAS painted?
2 Have they caught the thieves yet? - Yes. Two men was arrested yesterday. (two men / arrest./ yesterday) //тут вроде всё хорошо
3 Did you build the garage yourselves? -No. The garage had been built before we moved in. (the garage / build / before we moved in) //аналогично
4 Why is Paul afraid of dogs? -He was bitten a dog when he was a little boy (he / bite / a dog / when he was a little boy) //не уверен в выборе past perfect.
5 Sarah is very ill. – She was taken to hospital last night. (she / take / to hospital last night)
6. This room is a disgrace. – It wasn’t cleaned for weeks. (it / not clean / for weeks)
7. Did you know about your surprise party? - No. It was arranged in secret. (it / arrange / in secret) //вообще наугад выбрал время
8. Are you going to drive to work today? - I can't, the car isn’t fixed yet. (the car / not fix / yet) //тоже не уверен - действие же в настоящем?
9. Has Tom got a job? - No. He was made redundant last month. (he / make redundant / last month)
10. Do you know her name? No, she wasn’t asked about her name. (ask / about her name / she) //опять запутался.

1 That's a beautiful picture. - Yes. It was painted by my mother.(It / paint / my mother) (т.к. действие совершено в прошлом) 2 Have they caught the thieves yet? - Yes. Two men were arrested yesterday. (two men / arrest./ yesterday) (их же двое, так что не was :)3 Did you build the garage yourselves? - No. The garage had been built before we moved in. (the garage / build / before we moved in)4 Why is Paul afraid of dogs? - He was bitten by a dog when he was a little boy (he / bite / a dog / when he was a little boy) (c временем все правильно, рассуждаем логически "когда он был маленьким" - это время уже давным-давно прошло и не имеет связи с настоящим, поэтому используем паст симпл)5 Sarah is very ill. – She was taken to hospital last night. (she / take / to hospital last night) 6 This room is a disgrace. – It haven't been cleaned for weeks. (it / not clean / for weeks) (предлог for указывает, что действие длилось в течении определенного времени, в данном случае, в течении нескольких недель и можем мысленно продолжить "Она не убиралась неделями (и сейчас тоже не убрана)", так что используем перфект)7 Did you know about your surprise party? - No. It was arranged in secret. (it / arrange / in secret) 8. Are you going to drive to work today? - I can't, the car has not been fixed yet. (the car / not fix / yet) (нет, не в настоящем :) повторяем время перфет, оно используется со словами already, just, yet, resently и т.п. Переводим "Я не могу, машину еще не починили", т.е. машина сломалась в прошлом и ее до сих пор не сделали  - действие началось в прошлом и продолжается в настоящем.)9 Has Tom got a job? - No. He was made redundant last month. (he / make redundant / last month) 10 Do you know her name? - No, she wasn’t asked about her name. (ask / about her name / she) (звучит странно, конечно, но я бы так и оставила))
