Answer: Palpable.
The word "palpable" has the idea of something that can be felt. The boys were in fear of something, therefore palpable makes the most sense rather than the other choices.
The answer is A Evaluation
The description talks about Richard's work, it resembles a manager's evaluation -mostly during training processes in some jobs-
Incorrect answers:
B Experience
Experience cannot be used as the correct word because all the information is related to Richard's work if in any case, a person would use experience, the expression should be in my experience working with Richard...
C) Guess
A lot of precise and concise elements are enlisted in this description which does not leave any space for expectations
D) Trial
Trial can only be used in a legal context and we do not have any evidence that this is a legal situation.
