Question

is this a sentence fragment?
although there are approximately one thousand species of bats around the world, only three practice hematophagy, or the consumption of blood for food.
yes
no

Explanation:

A sentence fragment is an incomplete sentence lacking a subject, verb, or complete thought. The given sentence has a dependent clause ("Although there are...world") and an independent clause ("only three...food") with a subject ("three" referring to bat species) and verb ("practice"), forming a complete thought. So it's not a fragment.

Answer:

no
