Answer:
a fallacy masquerading as a valid inference.
Step-by-step explanation:
A Fallacy can be defined as a mistaken belief which is based on faulty argument.
Valid inferences are those inferences in which even if some parts are false but conclusion is true. In such fallacies, validity is not based on the truth but how an inference is established.
In the given case, the argument is an example of a fallacy masquerading as a valid inference because though the information provided is true but the conclusion is faulty. It may be true to say that many who had experience of severe fall become averse to climbing afterwards but it is false to say that Anthony will experience the same.
So, the argument is a fallacy masquerading as a valid inference.
