[textarea] ­1. The statement that "the higher pressures in this bottommost layer were not expect to change the perovskite's geometry" (see highlighted text) functions in thepassage

Explanation

A. suggests that the highlighted text serves as evidence or support for a claim regarding the tightly packed geometry of magnesium silicate perovskite. However, the highlighted statement itself does not directly assert or discuss the tightly packed geometry of perovskite. Instead, it mentions that scientists did not expect the geometry of perovskite to change under higherpressures.

B. suggests that the highlighted text serves as a premise supporting the claim that scientists incorrectly assumed the abundance of heavy elements within perovskite. However, the highlighted text does not directly address the abundance of heavy elements within perovskite. Instead, it focuses on scientists' expectations regarding the behavior of perovskite
