Statement: “If a doctor’s degree is your ambition, choosing a good guidance institute is half the job done.” Assumptions: I. Without proper guidance, it is very hard to become a doctor. II. An institute alone cannot ensure success; the student's effort is also essential.

Introduction / Context:
The line claims that selecting a good institute completes “half the job”, implying other factors must complement it. We must test which assumptions are required.

Given Data:
The statement emphasises the value of a “good guidance institute” but does not declare guidance to be absolutely necessary.

Concept / Approach:
“Half the job done” implies the institute is important but not sufficient.

Step-by-Step Solution:
I: Saying “very hard without guidance” is stronger than necessary. The statement promotes guidance but does not claim impossibility or extreme difficulty without it. Not implicit.II: If the institute covers only “half”, the remaining half must be student effort and other inputs. Hence II is implicit.

Verification / Alternative check:
Advertisements often balance necessity and sufficiency subtly; here, sufficiency is denied by “half”.

Why Other Options Are Wrong:
Options asserting I (alone or with II) overstate the claim.

Common Pitfalls:
Reading “important” as “indispensable” or “sufficient”.

Final Answer:
Only assumption II is implicit.
