Question

1. King Krishnadeva Raya would perform heavy
exercises every morning. (Use 'used to)
2.They advised the king to regulate his diet.
(Pick out the infinitive)​

Answer 1

Answer:

1.  King Krishnadeva Raya used to perform heavy exercises every morning.

2. They advised the king to regulate his diet. - to regulate is the infinitive.

Explanation:

In the first sentence, used to has been used to replace would.  

In the second sentence an infinitive has to be picked out. An infinitive is a ‘grammatical term’. It usually uses the word ‘to’. The verbs with ‘to’, like- to go, to eat, to sleep are called infinitives as they do not have a specific tense and those without ‘to’ are known as bare infinitives. Here in this sentence ‘to regulate’ denotes the infinitive verb that has been used. The two simple sentences have been combined and made into one ‘simple sentence’ using ‘to’.
