Answer 1

1. Anna WAS LOOKING at the departure board while the twins WERE STANDING in the queue. (Past Continuous, так как мы говорим об одновременных действиях + есть слово-подсказка while (пока/в то время как)

2. Eram DIDN'T HAVE anywhere to live.

(Past Simple, т. к. говорится о каком-то моменте в прошлом)

3. Daniel WAS SHOWING the tribesmen round the park when they STARTED hunting squirrels.

(Past Continuous и Past Simple, так как несколько действий в прошлом происходили в одно время.)

4. Max HAD already BEEN WAITING for six hours, before they ANNOUNCED the reason for the delay.

(Past Perfect Continuous, так как есть слово-подсказка: for (в течение…) и идет обозначение первичного действия, т.е. которое началось раньше;второй глагол в Past Simple, так как какое-то действие произошло в прошлом)
