Model's response = The word "Abracadabra" contains 6 vowels. The vowels are: A, a, a, a, a, and a.
Trustworthiness score = 0.6842228802750124
Explanation = This response is untrustworthy due to a lack of consistency in possible responses from the model. Here's one inconsistent alternate response that the model considered (which may not be accurate either):
5.

Model's response = Let me count the vowels in 'Abracadabra':
A-b-r-a-c-a-d-a-b-r-a

The vowels are: A, a, a, a, a

There are 5 vowels in the word 'Abracadabra'.
Trustworthiness score = 0.9378276048845285
Explanation = Did not find a reason to doubt trustworthiness.
