March is a transitional month and can bring snow or warm weather. Last week saw balmy weather that ended with a bitter snap. No lasting damage was done and the trees and bushes that had shown the first sign of green and blossom bounced back. Spring flowers had appeared, and daffodils, hyacinths and prim- roses were an incredible sight in gardens and parks. The freeze put the burst of spring flowers on temporary hold.

Question: The warm weather triggered an early burst of spring flowers.
Options:
A. true, B. false, C. uncertain
Answer: "C"
