what text structure is mainly used in \super soil: the mystery of terra preta\?

b. cause and effect
c. problem and solution
d. sequence of events

Explanation:

First Sub - Question (Select TWO phrases)

To solve this, we assume that Part A (not shown) is related to the soil's unsuitability for farming. Phrases that show the soil's negative impact on plants or its lack of nutrients would support this. "harmful to plants" (B) directly says the soil is bad for plants, and "poor in nutrients" (C) shows the soil lacks necessary elements for plants, both supporting the idea of the soil being unsuitable for farming. "sandy, reddish dirt" (A) is just a description, "year after year" (D) is about time, and "attempt to farm" (E) is about the action of farming, not the soil's quality.

In the text "Super Soil: The Mystery of Terra Preta", if we consider the context (even without full text), "Problem and solution" (C) is a common structure when a problem (like poor soil) and its solution (terra preta as super soil) is presented. "Compare and contrast" (A) would need two things compared, "Cause and effect" (B) focuses on reasons and results, and "Sequence of events" (D) is about chronological order, which is less likely here compared to problem - solution.

Answer:

B. harmful to plants, C. poor in nutrients
