Rearrange the parts to make a meaningful sentence.

P. most birds build their nests

Q. reach their eggs

R. high in the trees where

S. snakes and cats cannot

Explanation

1. 01

   P has the subject and the verb. R says where, and "where" must be followed by a clause.

2. 02

   S starts that clause, "snakes and cats cannot", and "cannot" needs a verb: Q "reach their eggs".

3. 03

   So the order is PRSQ: "Most birds build their nests high in the trees where snakes and cats cannot reach their eggs."
