Question

Which of the following conclusions can be drawn on the basis of facts mentioned in the given passage?

• A. Chemoautotrophic organisms with the help of carbon generate organic compounds.
• B. Life is not possible without carbon.
• C. Some of the micro-organisms on Earth can feed on inorganic compounds.
• D. Gale Crater contains not only hydrogen, oxygen and phosphorus but also carbon dioxide.

Hint:

Multiple correct facts may appear together in RC passages; ensure you check each option separately against the text.

Answer 1

The Correct Option is C

From the passage: - It states: "Some micro-organisms on Earth, for example, can feed on inorganic compounds, such as what are found inside rocks." \(\Rightarrow\) supports (c). - It also states: "Analysis shows the Gale Crater rock contains carbon dioxide, in addition to hydrogen, oxygen, phosphorus, sulphur and nitrogen." \(\Rightarrow\) supports (d). Option (a) is incomplete since passage allows life even without carbon present. Option (b) is wrong for the same reason. \[ \Rightarrow \boxed{(c) \text{ and } (d)} \]
