Answer 1

The gaps are filled as follows:

Mobile phones take up much more battery power when they are in vibration mode than when the ringtone is on.Keep brightness to a minimum, and switch off your bluetooth at times when you are not sharing files.

* For the first blank, 'they' is selected as the subject 'mobile phones' is a plural one.

* In the second one, contrasting situations are provided so 'on' is the correct word.

* The conjunction 'and' is the most suitable one for connecting two independent clauses in the third case.

* The last blank demands a preposition and 'at times' is a perfect phrase in this context.
