Question

select the correct answer.
rashid is conducting a seminar on the importance of coral reefs. which point should he include?
a. that corals can be picked from the sea and sold
b. that corals are poisonous and can be used for pest control
c. that corals have a hard exoskeleton that can be used for construction of buildings
d. that corals are impervious to damage
e. that corals provide economic assistance to coastal populations through fisheries

Explanation:

• Option A: Picking corals from the sea and selling them is a negative and harmful activity, not an importance of coral reefs.
• Option B: Corals are not poisonous and not used for pest control.
• Option C: Corals have a hard exoskeleton. Historically, in some places, coral skeletons (e.g., coral stone) have been used in construction (though this is not a sustainable practice now in most cases as coral reefs are important ecosystems).
• Option D: Corals are not impervious to damage. They are sensitive to factors like climate change (ocean warming and acidification), pollution, and physical damage.
• Option E: While coral reefs can support fisheries which provide economic benefits to coastal populations (not through "favoritism" but as a natural resource), option C directly relates to a physical characteristic (hard exoskeleton) that has had historical (though now often discouraged in modern conservation - minded contexts) use in construction.

Answer:

C. that corals have a hard exoskeleton that can be used for construction of buildings
