While researching a topic, a student has taken the following notes:

Platinum is a rare and expensive metal.
It is used as a catalyst for chemical reactions.
Platinum catalysts typically require a large amount of platinum to be effective.
Researcher Jianbo Tang and his colleagues created a platinum catalyst that combines platinum with liquid gallium.
Their catalyst was highly effective and required only trace amounts of platinum (0.0001% of the atoms in the mixture).
The student wants to explain an advantage of the new platinum catalyst developed by Jianbo Tang and his colleagues. Which choice most effectively uses relevant information from the notes to accomplish this goal?
Choose 1 answer:
Choose 1 answer:
(Choice A) Like other platinum catalysts, the new platinum catalyst requires a particular amount of the metal to be effective.
A
Like other platinum catalysts, the new platinum catalyst requires a particular amount of the metal to be effective.
(Choice B) Platinum is a rare and expensive metal that is used as a catalyst for chemical reactions; however, platinum catalysts typically require a large amount of platinum to be effective.
B
Platinum is a rare and expensive metal that is used as a catalyst for chemical reactions; however, platinum catalysts typically require a large amount of platinum to be effective.
(Choice C) While still highly effective, the new platinum catalyst requires far less of the rare and expensive metal than do other platinum catalysts.
C
While still highly effective, the new platinum catalyst requires far less of the rare and expensive metal than do other platinum catalysts.
(Choice D) Researcher Jianbo Tang and his colleagues created a platinum catalyst that combines platinum, a rare and expensive metal, with liquid gallium.
D
Researcher Jianbo Tang and his colleagues created a platinum catalyst that combines platinum, a rare and expensive metal, with liquid gallium.

1 answer

(Choice C) While still highly effective, the new platinum catalyst requires far less of the rare and expensive metal than do other platinum catalysts.

This choice effectively uses the information from the notes to highlight the advantage of the new platinum catalyst developed by Jianbo Tang and his colleagues. It emphasizes that the new catalyst is highly effective while requiring only trace amounts of platinum, making it more efficient and cost-effective compared to traditional platinum catalysts.
