Question

Tap an adverbial phrase of frequency to fill in the blank.
'You can join us .'

Answer 1

An adverbial phrase of frequency is a group of words that answers the question 'How often?'. Here, the phrase 'on Saturdays and Sundays' tells us how often 'you can join us' for the sessions. The other options are wrong because they answer the question 'When?' but not 'How often?'.
