Answer

To solve the question of which option will fail to check the problem of population explosion, we can analyze each option step by step.

### Step-by-Step Solution:

1. **Understanding Population Explosion**:
- Population explosion refers to the rapid and dramatic increase in the world's population over a short period. It is characterized by a significant rise in the number of people, which can lead to various socio-economic issues.

**Hint**: Remember that population explosion is about rapid growth, and understanding its definition is crucial.

2. **Analyzing the Options**:
- **Option A: Acquiring one-child norm**:
- This policy restricts families to having only one child. It is a direct measure to control population growth and would effectively help in checking the population explosion.

**Hint**: Consider how limiting family size can impact overall population growth.

- **Option B: Decreasing the marriageable age**:
- Lowering the marriageable age can lead to earlier marriages and potentially more children being born at a younger age. This would likely contribute to an increase in population rather than help control it.

**Hint**: Think about how earlier marriages might affect family planning and birth rates.

- **Option C: Use of contraceptive methods**:
- Contraceptive methods are designed to prevent unwanted pregnancies and control birth rates. This is a well-recognized strategy to manage population growth effectively.

**Hint**: Recall how contraceptives can empower individuals to make choices about reproduction.

- **Option D: Providing education to the people**:
- Education, particularly regarding family planning and reproductive health, can lead to better decision-making about childbirth. Educated individuals are often more aware of and utilize family planning methods, which helps in controlling population growth.

**Hint**: Consider how education can influence societal norms and personal choices regarding family size.

3. **Conclusion**:
- After analyzing all options, it is clear that **Option B: Decreasing the marriageable age** will fail to check the problem of population explosion, as it may lead to an increase in birth rates.

### Final Answer:
The correct answer is **Option B: Decreasing the marriageable age**.
