Question 4

Over 600,000 square kilometers (232,000 square miles) of Amazon rainforest have been destroyed since 1970.

This statement is a fact that can be verified through data and research concerning deforestation in the Amazon River Basin.

A) Deforestation causes global warming.

This statement reflects an opinion rather than a universally accepted fact. While many scientists agree there is a correlation between deforestation and climate change, the direct causation of global warming solely from deforestation is debated and not an indisputable fact.

B) The rainforest is essential to life on Earth.

This statement is generally accepted as true but is phrased as an opinion because it reflects a belief about the importance of the rainforest rather than a specific, quantifiable fact. While the ecological role of the rainforest is critical, the statement lacks empirical evidence to be classified strictly as a fact.

C) South American countries must stop deforestation of the rainforest immediately.

This statement is an opinion expressing a moral or ethical imperative rather than a fact. It advocates for action but does not provide factual data or evidence to support the necessity of immediate action, thus making it subjective.

D) Over 600,000 square kilometers (232,000 square miles) of Amazon rainforest have been destroyed since 1970.

This statement is a fact supported by statistical data regarding the extent of deforestation in the Amazon rainforest. It provides specific figures that can be verified through research.

Conclusion

The correct answer, D, is definitively a factual statement that can be backed by empirical data regarding deforestation. In contrast, the other options represent opinions or beliefs that lack the same level of verifiable evidence, thus failing to qualify as objective facts.
