Verbs that take the command subjunctive -- suggest, require, propose, demand, etc. -- may also be followed by a NOUN.
Correct: The law requires that every passenger wear a seat belt.
Correct: The law requires a seat belt for every passenger.

In the OA, the possibility correctly serves as the direct object of suggest.

Is it correct to say 'comprises' here and not 'comprise' ??

In the OA, comprises (singular) agrees with its subject the normal life span (also singular).

As per your posts about subjunctive, there should be BARE INFINITIVE. Bit here they used 'comprises' why is this case different? In your example above, you used bare infinitive 'wear'.

The doctor suggested that John eat a full serving of vegetables every day.
Here, the that-clause in red constitutes a RECOMMENDATION.
WHAT did the doctor suggest?
He suggested THAT JOHN EAT A FULL SERVING OF VEGETABLES EVERY DAY.
Since the that-clause constitutes a RECOMMENDATION, the command subjunctive is required.
For this reason, the verb in the that-clause -- eat -- is in its bare infinitive form.

OA: suggest the possibility that the normal human life span comprises an even number of days
Here, the that-clause in blue does not constitute a recommendation but serves as an ADJECTIVE describing the possibility.
What KIND of possibility?
The possibility THAT THE NORMAL HUMAN LIFE SPAN COMPRISES AN EVEN NUMBER OF DAYS.
Since the that-clause does NOT constitute a recommendation, the command subjunctive is not warranted.
