Correct option is C
Statement: On his second visit, the doctor changed the prescription.
Assumptions:
Assumption I: The patient did not show improvement with the earlier prescription.
Assumption II: The patient did not take the earlier prescription seriously.
Analyze the assumptions:
Assumption I: The patient did not show improvement with the earlier prescription.
This is a reasonable assumption because doctors typically change prescriptions if the current treatment isn't effective. Therefore, this assumption is implicit.
Assumption II: The patient did not take the earlier prescription seriously.
This assumption is not necessarily implied by the statement. The change in prescription could have been due to medical reasons rather than the patient's non-compliance. There’s no indication in the statement that the patient failed to follow the earlier prescription.
Conclusion: Only Assumption I is implicit.
