Answer to Question 1

Answer: A

Answer to Question 2

Answer: When using the half-life method, scientists assume a closed system where there has been no addition or loss of parent or daughter products. If this assumption is not true, age determination will be wrongthe age will be either too old or too young. Another limitation exists for rocks subjected to metamorphism in which the rock's age has been reset. Making sure that a good sample is used, and careful cross checking between samples increases accuracy.
