HOTS English Primary 3 Comprehension

Read the passage and decide whether the statement is TRUE or FALSE, and select the reason that BEST supports your answer. Passage: "For years, scientists believed that dinosaurs were slow, cold-blooded animals. However, recent fossil evidence showing growth rings in dinosaur bones and feather imprints has led many researchers to conclude that at least some dinosaurs were warm-blooded and may have been more agile than previously thought. Not all scientists agree — some argue the evidence is insufficient for a definitive conclusion." Statement: "It is now established scientific fact that all dinosaurs were warm-blooded."

A False — the passage states that the evidence is disputed and some scientists argue it is insufficient for a definitive conclusion
B True — fossil evidence of growth rings proves all dinosaurs were warm-blooded
C False — scientists have proven that dinosaurs were cold-blooded
D True — the passage says many researchers have concluded dinosaurs were warm-blooded
