Statement: The human organism grows and develops through stimulation and action. Conclusions: I) An inert human organism (without stimulation/action) cannot grow and develop. II) Human organisms do not respond to stimulation and action.

Introduction / Context:The premise makes a positive claim: growth/development occurs via stimulation and action. We must see which conclusions necessarily follow, paying attention to negations and contradictions.

Given Data / Assumptions:

• Growth and development are contingent on stimulation/action.
• No suggestion that stimulation/action are ineffective.

Concept / Approach:If growth requires stimulation/action, the absence of these would preclude growth—this supports Conclusion I (a form of contrapositive intuition). Conclusion II directly contradicts the premise by stating that humans do not respond to stimulation/action.

Step-by-Step Solution:1) From the dependency, infer that inertness (no stimulation/action) prevents growth ⇒ I follows.2) II is inconsistent with the stated mechanism (respond and grow), so II does not follow.

Verification / Alternative check:Even if some growth might occur endogenously, the statement posits stimulation/action as the route; we accept that framing for the problem.

Why Other Options Are Wrong:“Both” is contradictory; “neither” ignores the clear logical support for I.

Common Pitfalls:Overcomplicating the reading with outside biology; keep to the logical structure given.

Final Answer:Only conclusion I follows.
