Question

fossil evidence provides a timeline of dinosaur existence and extinction. there are two prevailing theories for the extinction of the dinosaurs. there is evidence to support each theory. a giant meteor slammed into earth, filling the atmosphere with debris and gases that changed the climate. an extreme volcanic eruption filled the air with debris and gases that changed earth’s climate. what should scientists do to settle this debate? study the effects of meteor impacts and volcanic eruptions on current climate change. study the effects of current climate change on animals descended from dinosaurs. vote on which theory is best supported by the current evidence. continue to look for evidence that will confirm one theory over the other.

Explanation:

To settle the debate between the two dinosaur extinction theories (meteor impact vs. volcanic eruption), scientists should continue to gather evidence that can confirm one theory over the other. Studying current climate change effects on modern animals or voting on theories is not scientific. Studying meteor/volcanic effects on current climate change doesn't directly address dinosaur extinction. Continuing to find confirming evidence is the proper scientific approach.

Answer:

Continue to look for evidence that will confirm one theory over the other.
