Passive to Active voice

Can someone explain why this sentence is considered passive voice. Also convert it to active voice.
"The recruits are tested and qualified for the finals".

Answer

There is Passive Voice in this sentence because:
1. The predicate of the sentence is in the Present Simple Passive (to be + Participle II).

2. The subject of the sentence is the logical object (the recruits).
3. The sentence can be reconstructed into the Active Voice (with the subject naming the performers of testing and qualifying):
They (i.e., the recruiters) test and qualify the recruits for the finals.
