Statement: “You need one who is as serious as you are, and equally dedicated.” Assumptions: I. Nothing significant can be achieved alone; at least one equally serious partner is needed. II. The statement specifically refers to a student and a teacher.

Introduction / Context:
The speaker emphasises the necessity of another person with matching seriousness and dedication. We assess the assumptions.

Given Data:
No roles are specified; only the need for a like-minded partner is asserted.

Concept / Approach:
An assumption must underlie the recommendation.

Step-by-Step Solution:
I: The advice presumes solo effort is inadequate and collaboration with an equally dedicated person is necessary. Implicit.II: Restricting the roles to student and teacher is unwarranted; it could be co-founders, colleagues, or teammates. Not implicit.

Verification / Alternative check:
The statement is role-agnostic; any dyad fits.

Why Other Options Are Wrong:
Options including II add specificity not present in the statement.

Common Pitfalls:
Assuming a particular relationship when the text is generic.

Final Answer:
Only assumption I is implicit.
