T4W1 TS Q12 – Selective High School

The Blue Mountains Water Skink is an endangered species, while the Eastern Water Skink has a thriving population.
Adnan and Mahati are studying both species in the Blue Mountains.

Adnan: “In the past twelve months, our experiment in the Blue Mountains recorded 73 Blue Mountains Water Skinks and 74 Eastern Water Skinks.”

Mahati: “That means the Blue Mountains Water Skink population has recovered and should no longer be considered endangered!”

Which one of the following sentences shows the mistake Mahati has made?

The Blue Mountains Water Skink’s recorded population was slightly lower than that of the Eastern Water Skink. The different seasons could affect how often each skink species is seen. Other species of skinks in the area may not have been identified yet. The results only describe one small area and do not represent the species’ total population.

Are you sure you want to leave?
