Question

preposition for the girl is kneeling on the grass

Answer 1

Answer:

The girl is kneeling down on the grass.

Explanation:

The reason why we have used no other preposition but down over here is because with the given word kneel the only appropriate preposition used is down . For Example : The captain commanded the soldiers to kneel down to start the training . Here we cannot use kneel upon , at , beneath , above , on , in etc. Hopefully the point is clear
