Cover crops such as crimson clover are frequently utilized to manage soil quality in agricultural ecosystems. Crimson clover has the capacity to fix nitrogen, an essential element for plant growth, into the soil. To evaluate this effect, researchers compared soil plots planted with crimson clover to plots that remained fallow. Their analysis revealed that the plots with clover exhibited significantly higher nitrogen concentrations. Given that the growth of subsequent crops is highly dependent on the availability of soil nitrogen, this outcome suggests that planting crimson clover between cash crop seasons ______

Which choice most logically completes the text?

  1. A
    is less labor-intensive than leaving the agricultural plots fallow.
  2. B
    will eliminate the need for any chemical fertilizers in the future.
  3. can increase the nitrogen available for future crops.Cevap
  4. D
    will decrease the amount of nitrogen in the soil over time.

Cevap

can increase the nitrogen available for future crops.
The text establishes two main points: first, that plots planted with crimson clover have higher nitrogen concentrations than fallow plots, and second, that subsequent crops rely on nitrogen for growth. It logically follows that planting crimson clover will increase the amount of nitrogen available for those subsequent crops.

Adım Adım Çözüm

1
Identify the key premises in the passage.
The passage establishes that crimson clover increases soil nitrogen compared to fallow soil, and that future crop growth depends on soil nitrogen levels.
Understanding the core facts is necessary to draw a logical conclusion.
2
Connect the premises to determine the logical next step.
If planting clover increases nitrogen, and future crops need nitrogen, then planting clover before future crops will supply them with more nitrogen.
This establishes the direct cause-and-effect relationship based only on text evidence.
3
Evaluate the choices to find the one that matches this link without overreaching.
The option asserting that clover can increase nitrogen for future crops is directly supported, while the others introduce unsupported claims or contradict the text.
SAT logical inference questions require selecting the most direct, non-speculative option.
