LessonsInduction: Complete and Incomplete Enumeration, Certainty and ProbabilityQuiz

An inductive argument has two stages: observations about individuals and a conclusion about the whole class.

Observations: human beings, horses, cattle, and other investigated animals were reported to move the lower jaw while chewing.
General conclusion: every animal moves its lower jaw in that manner.

The conclusion extends to individuals that were never examined. The central question is whether the investigated instances are sufficient to establish that extension.
