Free SAT® Practice Question (mock)

Researchers investigating natural plant defenses have identified specific bacterial compounds called cyclic lipopeptides (CLPs) that may serve as indicators of a plant's ability to withstand fungal infections. Dr. Mei Zhang and her team discovered that in agricultural crops, nearly all plants with detectable CLP levels demonstrated significant resistance to common fungal pathogens. However, their experiments revealed that in forest ecosystems, certain tree species can produce CLP-like molecules through their own metabolic processes without acquiring enhanced fungal resistance. The team's findings suggest a potential method for agricultural scientists to assess plant disease resistance by measuring CLP levels.

Based on the text, Dr. Zhang and her colleagues would most likely agree with which statement about cyclic lipopeptides (CLPs)?

A) Their presence is more reliable as an indicator of resistance to fungal infections in forest soils than in agricultural soils.

B) Their absence from agricultural soil would indicate that plants grown in the soil probably cannot withstand fungal infections.

C) They should be used as indicators of plants' resistance to fungal infections if detected in agricultural soil but not if detected in forest soil.

D) They don't consistently reach detectable concentrations in either agricultural or forest soils to be useful as indicators of resistance to fungal infections.
