Free SAT® Practice Question

To combat the increasing problem of soil erosion in agricultural lands, environmental scientists have developed biodegradable mulch films made from plant-derived cellulose. These films are designed to protect topsoil from water and wind displacement by creating a protective barrier on the soil surface. Examining the protective properties of various commercially available cellulose-based mulch films, Dr. Amelia Rodriguez and her team discovered that in comparison with two starch-based cellulose mulch films, an algae-derived cellulose mulch film demonstrated a higher water retention capacity, which reflects how effectively a soil covering prevents moisture evaporation under consistent rainfall and soil conditions. The finding suggests that _____

Which choice most logically completes the text?

A. in contrast to the two starch-based cellulose mulch films, the algae-derived cellulose mulch film can significantly reduce moisture evaporation, provided rainfall patterns and soil compositions are uniform.

B. the two starch-based cellulose mulch films likely possess similar potential for increasing water and wind displacement of topsoil, thus improving the potential productivity of agricultural crops.

C. agricultural plots covered with the algae-derived cellulose mulch film may be subject to water displacement to a lesser extent than agricultural plots covered with either of the two starch-based cellulose mulch films.

D. starch-based mulch films may facilitate greater soil moisture retention in agricultural plots than is possible for agricultural plots covered with algae-derived cellulose mulch films.
