Question

read the passage. the boiling river, locally known as shanay - timpishka, extends four miles through the amazon rainforest in peru. although the river doesnt actually boil, it averages temperatures of 186 degrees fahrenheit. since there arent any volcanoes close to the river, scientists hypothesize that the water is heated when it seeps deep into faults in the ground and is exposed to geothermal energy sources. pressure builds from below, forcing the water back up into the river where steam steadily rises from the water’s surface. the extreme heat of the boiling river has consequential effects on nearby plant life. researchers who studied vegetation along the river noticed less growth near the hotter parts of the river. the elevated temperatures in the soil and air limit the number of plant species that can survive such harsh conditions. yet plants like the giant ceiba tree are found in the area because they can tolerate such hot environments. which statement best describes the relationship between the first and second paragraphs? the first paragraph provides an overview of the boiling river’s role in peruvian culture, whereas the second paragraph focuses on the priorities of american researchers. the first paragraph introduces the positive environmental impacts of the river’s unusual temperature, and the second paragraph pivots to its negative effects. the first paragraph explains the natural causes of the hot water, while the second paragraph details how human activity affected the water’s temperature. the first paragraph establishes context about the river’s unique properties, and the second paragraph describes the environmental impacts of the river’s extreme temperatures.

Explanation:

The first paragraph introduces the Boiling River, its temperature, and the cause of its heat (unique properties). The second paragraph details effects on plant life (environmental impacts of extreme temperatures), making this the correct relationship.

Answer:

The first paragraph establishes context about the river’s unique properties, and the second paragraph describes the environmental impacts of the river’s extreme temperatures.
