Answer to Question 1

T

Answer to Question 2

ANS:A
few years ago, it was discovered that the lead shot that is used in shotgun shells was killing
waterfowl long after the hunting season was over. Waterfowl do not know the difference between lead
shot and the small rocks they must eat to grind the seeds and plant materials that make up their food.
When lead shot is eaten, it is gradually absorbed into the body, causing lead poisoning to occur.
Eventually, it causes the death of the affected birds. Simply replacing lead shot with steel shot
eliminates this problem.
