The correct answer is: C. Either I or II is implicit.
The statement “The patient’s condition would improve after operation” does not provide enough information to determine whether or not the patient can be operated upon in this condition. It is possible that the patient can be operated upon, in which case assumption I is implicit. It is also possible that the patient cannot be operated upon, in which case assumption II is implicit. Therefore, either assumption I or assumption II is implicit, but not both.
Here is a more detailed explanation of each option:
- Option A: Only assumption I is implicit. This option is incorrect because assumption II is also possible. For example, the patient may have a condition that can only be treated with surgery, in which case the doctor would have to operate on the patient even if it is risky.
- Option B: Only assumption II is implicit. This option is incorrect because assumption I is also possible. For example, the patient may have a condition that can be treated with medication, in which case the doctor would not have to operate on the patient even if it is safe.
- Option C: Either I or II is implicit. This option is correct because either assumption I or assumption II is possible.
- Option D: Neither I nor II is implicit. This option is incorrect because assumption I or assumption II is possible.
- Option E: Both I and II are implicit. This option is incorrect because assumption I and assumption II are not necessarily both true.
