Meaning of exploit (verb)

[Bhikkhu1991a]

Hello,

An uncountable word has been wrongly treated as a countable one in the sentential example. The noun word “potential” is uncountable according to http://www.oxfordadvancedlearnersdictionary.com/dictionary/potential and
http://dictionary.cambridge.org/dictionary/british/potential_2. Could you please look into this matter?

Here is an excerpt from Test # TOEFL/M1-(http://www.english-test.net/toefl/vocabulary/meanings/001/toefl-test.php):

Meaning of exploit (verb)
to use for one's selfish purpose

Example

There is a superficial choice between abandoning many DRAs or in making new investments to exploit their potentials.

Thank you.
