Question

1. the giant redwoods and the giant sequoia are different. the giant redwood is also called the coastal redwood. this tree differs from the giant sequoia because of the environment it needs. giant or coastal redwoods grow best in moist, humid climates of the northern california coast. these trees are usually taller than the sequoias. but the sequoias weigh substantially more.
2. the sequoias branches are much wider, and their bark can grow three times as thick, up to 3 feet. the giant sequoias grow best in higher elevations. they grow along the western slope of the sierra nevada mountains. they need periodic dry heat to trigger their cones to open and release seeds. they live up to 1 000 years longer than the giant redwoods.

in paragraph 1, the word substantially means
a seriously
b as a result
c considerably
d in accordance

Explanation:

The word "substantially" means "considerably". In the context of the sentence "But the sequoias weigh substantially more", it implies a large or significant amount. "Seriously" (A) doesn't fit the context of weight comparison. "As a result" (B) is a phrase indicating cause - effect and not relevant here. "In succession" (D) means one after another and is also not appropriate for describing weight.

Answer:

C. considerably
