alleryEach apple is paired with exactly one orange and none is left over. What does this show?
AThe apples weigh more
BThe groups match in size
CThe oranges are bigger
DThe count must be odd
Answer & Solution
Correct answer: B. The groups match in size
1. Pairing one-to-one without leftovers is a one-to-one correspondence.
2. Such pairing shows the two groups have the same cardinality.
3. It says nothing about weight, size of fruit or oddness.
