I was wondering if you could let me know which one of the listed choices fits better in my self-made sentence below:
CEO to the applicants of achieving a job: In order to get this job, you must first prove your potentials and demonstrate us your good customers service skills. You must be able to effectively communicate over the phone.
Applicants pass their tests and then the CEO asks the examiner: How was the guy in blue shirt?
The examiner answers: Awful; I could easily see his _______ with my own eyes even before beginning of the contest.
incapabilities
inabilities
For me, both work here properly, but they differ the meaning of the sentence. Do you confirm it?
