Question

Before that day, ---- of taking up sketching

Answer 1

Answer:

before that day, all of taking up sketching

Answer 2

Before that day, I never thought of taking up sketching.

Explanation:

The given sentence is incomplete as it does not have a main verb. To insert a main verb a subject is also required to complete the normal sentence structure SVO - subject + verb + object.  

In the given sentence, ‘Before that day, ---- of taking up sketching’, a subject and verb is required.  

It thus could be ‘I never thought’ where I is the subject, ‘thought’ the verb and ‘sketching’ the object. ‘Before that day’ is an adverb phrase of time.
