Introduction / Context:
This question checks the correct use of concessive vs. conditional connectors. “Even if” introduces a hypothetical condition, while “even though/although” concedes a fact. Because the result clause is in the past (“could not succeed”) and the effort actually occurred, the concessive “even though” is required, not the conditional “even if”.
Given Data / Assumptions:
- Event happened: the doctor tried hard.
- Outcome: the patient could not be saved.
- Connector used: “Even if …” (wrong for factual concession).
Concept / Approach:
- Use “even though/although” to concede a real, completed action.
- Use “even if” for imagined or possible situations.
- Therefore, Segment A should read “Even though the doctor …”.
Step-by-Step Solution:
Identify whether the subordinate clause states fact or possibility.Replace “if” with “though/although” for factual concession.Re-read for coherence in past time: “Even though the doctor put in …, he could not succeed …”.
Verification / Alternative check:
Switch to hypothetical: “Even if the doctor puts in his best efforts, he may not succeed.” That different meaning confirms the error in the original.
Why Other Options Are Wrong:
B–D: Correct past-time description with appropriate collocation “put in efforts”.E: Not applicable because A is erroneous.
Common Pitfalls:
Confusing concessive (“though”) and conditional (“if”) clauses.
Final Answer:
Even if the doctor
