Zorluk: OrtaSingle-Sentence Inferences

Read the following sentence from a historical study on soil conservation practices:

"While early twentieth-century agronomists maintained that continuous leguminous crop rotation would permanently replenish soil nitrogen levels without degrading mineral trace elements, subsequent long-term soil assays demonstrated that prolonged monocultural legume planting accelerates the acidification of subsoil strata, thereby reducing the bioavailability of essential micronutrients such as molybdenum."

Based on the sentence above, which of the following can be most reasonably inferred regarding prolonged leguminous crop cultivation?

  1. It can lead to a decrease in the accessibility of certain essential micronutrients in the subsoil.Cevap
  2. B
    Early twentieth-century agronomists intentionally ignored the chemical impacts of subsoil acidification.
  3. C
    Long-term soil assays established that leguminous crop rotation completely fails to restore soil nitrogen levels under any circumstances.
  4. D
    It causes subsoil strata to become progressively less acidic over extended periods of cultivation.
  5. E
    Early twentieth-century agronomists considered molybdenum to be the sole trace element affected by monocultural planting.

Cevap

Extended leguminous crop cultivation can lead to a decrease in the accessibility of certain essential micronutrients in the subsoil.
The sentence directly links prolonged monocultural legume planting to the acceleration of subsoil acidification and the subsequent reduction in bioavailability of essential micronutrients like molybdenum. Therefore, it strictly supports the inference that extended cultivation can reduce the accessibility of certain essential micronutrients in the subsoil.

Adım Adım Çözüm

1
Analyze the target sentence for direct facts and conditional relationships.
The sentence indicates that prolonged monocultural legume planting 'accelerates the acidification of subsoil strata, thereby reducing the bioavailability of essential micronutrients such as molybdenum.'
Single-sentence inference questions require strictly supported conclusions derived directly from the stated relationships.
2
Match the core claim with the correct inference option.
Reduced bioavailability of essential micronutrients directly means that these micronutrients (such as molybdenum) become less accessible in the subsoil.
'Bioavailability' refers to accessibility/usability by organisms, matching the valid inference.
3
Eliminate options that extrapolate, use extreme language, or misrepresent contrast pivots.
Claims regarding intentional disregard, absolute failure of nitrogen restoration, reversed acidity trends, or misattributed early beliefs are unsupported by the sentence.
GMAT RC inference requires avoiding out-of-scope assumptions and extreme claims not strictly backed by text.
