Question 21

Its precipitation levels

The text does not provide specific details about the precipitation levels of the Amazon Rainforest, making this the correct answer to the question.

A) Its total area

The paragraph clearly states that the Amazon Basin covers over 2.3 million square miles, which directly addresses its total area. Therefore, this option is mentioned in the extract.

B) Its water features

The extract notes that the Amazon River is the second largest in the world and contains more than one-fifth of the world's fresh water. This indicates that water features are explicitly mentioned in the context of the Amazon Rainforest.

C) Its precipitation levels

While the text describes the rainforest as humid and warm with a high amount of rainfall, it does not provide specific information regarding the precipitation levels. This absence makes this option the correct answer.

D) Its extinct species

The paragraph discusses various species living in the Amazon Rainforest but does not mention any extinct species. Thus, this option is not mentioned in the extract.

Conclusion

The correct answer is C, as the text does not specify precipitation levels despite mentioning the humid and rainy conditions of the Amazon Rainforest. Options A and B are confirmed through clear details in the extract, while D, although indirectly related, does not pertain to extinction but rather focuses on current biodiversity.
