Let's analyze each question step by step.

### Question 18
The question asks about the factors that influence scientists' understanding of natural relationships between organisms and their environments. The options provided are:

1. Development of bioengineered organisms
2. Value of the natural resources in the region
3. Availability of undisturbed regions in the world
4. The institutional value of the organisms in the ecosystem

**Analysis:**
- The development of bioengineered organisms may help in understanding certain aspects but does not directly relate to natural relationships.
- The value of natural resources is more about economic aspects rather than ecological understanding.
- The availability of undisturbed regions is crucial for studying ecosystems in their natural state, which can provide insights into natural relationships.
- The institutional value of organisms may pertain to conservation efforts but does not directly influence understanding.

**Conclusion:** The best answer is **availability of undisturbed regions in the world**.

### Question 19
This question discusses the ecological impact of clearing over 500 acres of forests for a new subdivision. The options are:

1. More species of birds and insects will inhabit the region
2. A drainage system will be built to limit erosion
3. The levels of carbon dioxide in the air will decline

**Analysis:**
- Clearing forests typically leads to habitat loss, which would likely result in fewer species of birds and insects, not more.
- A drainage system may be built, but this is a response to the clearing rather than a natural outcome.
- Deforestation generally increases carbon dioxide levels in the atmosphere due to the loss of trees that absorb CO2.

**Conclusion:** The most accurate expectation is **a drainage system will be built to limit erosion**.

### Question 20
This question asks which situation is most likely to have the lowest infiltration-runoff ratio. The options are:

1. A beach
2. A grassland
3. A paved parking lot
4. Mowed soccer field

**Analysis:**
- A beach typically has high infiltration due to sand, leading to a higher infiltration-runoff ratio.
- Grasslands also have good infiltration due to vegetation and soil structure.
- A paved parking lot has very low infiltration because the surface is impermeable, leading to high runoff.
- A mowed soccer field has some vegetation, allowing for moderate infiltration.

**Conclusion:** The situation most likely to have the lowest infiltration-runoff ratio is **a paved parking lot**.

### Summary of Answers
- **Question 18:** Availability of undisturbed regions in the world
- **Question 19:** A drainage system will be built to limit erosion
- **Question 20:** A paved parking lot
- **Question 18:** Availability of undisturbed regions in the world - **Question 19:** A drainage system will be built to limit erosion - **Question 20:** A paved parking lot
