Answer 2

Answer:

1. Please pay attention to your studies.

2. He is angry at my behaviour.

3. Hydrogen consists of water.

4. Flour is made from wheat.

Explanation: As we know,

• The phrase 'pay attention to' is a common one which means whenever we are listening or watching closely to what someone else is saying or doing. Thus, it takes preposition 'to' with it.
• When the emotion of anger is directed towards a person then preposition 'with' is used. But if the same emotion is directed towards an object, noun then the preposition 'at' is applied. Thus, 'at' is the accurate choice.
• The phrase 'consists of' is a common one which means 'to be made or composed of something'. Apparently, hydrogen is formed of water.
• We use preposition 'from' to display the material that something is made from. Example: Curd is made from milk.

Hence, the prepositions 'to, at, of, from' constitute the correct answer.
