Answers to Punch

1. Answer : A

Solution : The opposite of Parsimonious is generous.

2. Answer :

Subtracting the second equation from the first gives you 4y = 4z, which is equivalent to saying that y â€“ z = 0. So actually there are two equations and three unknowns, and therefore there are an infinite number of solutions.
