Final answer:
The claim that Sherlock Holmes is in a hospital laboratory because he's a medical student is false; Holmes is a detective, not a medical student, although he frequently works alongside medical professionals.
Step-by-step explanation:
The statement that Sherlock Holmes spends time in the hospital laboratory because he is attending medical school and studying to be a doctor is False. Sherlock Holmes, a character created by Sir Arthur Conan Doyle, is a consulting detective known for his profound skills in logical reasoning, observation, and forensic science, not for attending medical school.
