Question

how does the coast redwood compare to the giant sequoia?
the coast redwood is a little shorter and much older.
they are both a little smaller than the dawn redwood.
the coast redwood tends to be taller, but the giant sequoia tends to be more massive and older.
they are members of the same genus.

Explanation:

To determine the correct answer, we analyze the characteristics of Coast Redwood (Sequoia sempervirens) and Giant Sequoia (Sequoiadendron giganteum). Coast redwoods are often taller, while giant sequoias are more massive (wider/trunk volume) and can be older. Let's evaluate each option:

• Option 1: "The coast redwood is a little shorter and much older." → Incorrect. Coast redwoods are generally taller, and giant sequoias can be older (or comparable in age ranges, but not "much older" for coast redwoods).
• Option 2: "They are both a little smaller than the dawn redwood." → Incorrect. Dawn redwood (Metasequoia glyptostroboides) is smaller than both; this misrepresents the comparison between coast redwood and giant sequoia.
• Option 3: "The coast redwood tends to be taller, but the giant sequoia tends to be more massive and older." → Correct. This aligns with their physical traits: coast redwoods reach greater heights, while giant sequoias have larger trunks (mass) and can live longer.
• Option 4: "They are members of the same genus." → Incorrect. Coast redwood is in Sequoia, giant sequoia in Sequoiadendron (different genera, though related in the Cupressaceae family).

Answer:

The option "The coast redwood tends to be taller, but the giant sequoia tends to be more massive and older." (the third option in the list)
