Answer:
He has not received proper medical training.
Step-by-step explanation:
This question refers to an excerpt from the comedy novel Three Men in a Boat (To Say Nothing of the Dog) written by Jerome K. Jerome. On pages 4-5, the narrator is reading about symptoms of different illnesses and thinks that he has almost all illnesses in the book. In the end, he can't feel his heartbeat and goes to the doctor, who prescribes him not to stuff up his head with things he doesn't understand.
The options you were given are the following:
- He has not received proper medical training.
- He is in a location where there is too much noise to hear anything.
- He is inclined to believe the worst about his health.
- He has symptoms of an illness that weaken his heartbeat.
Based on the information about the excerpt, we can conclude that the narrator is unable to find his own heartbeat because he has not received proper medical training, unlike his doctor, who knows that there is nothing physically wrong with him. As he hasn't received training, he can't properly diagnose himself and believes he has symptoms he doesn't actually have.
