Question

in a 2020 paper, arya udry et al. cautioned that although similarities in the isotopic signatures of elements detected in marss atmosphere and in martian meteorites recovered on earth make it tempting to treat the geochemical properties of the meteorites as those of marss interiors, marss geology cannot be ascertained based solely on meteorite sample analyses. which choice completes the text with the most logical and precise word or phrase? a proxies for b contrivances of c catalysts of d deterrents to

Explanation:

The text discusses using Martian meteorites to understand Mars. "Proxies for" means substitutes or representatives. Meteorites are substitutes for Mars's interiors as Mars's geology can't be known just from meteorite analyses. "Contrivances of" (devices of) and "catalysts of" (starters of) don't fit. "Deterrents to" (things that stop) is wrong.

Answer:

A. proxies for
