In a nature reserve in India, people are sometimes attacked by tigers. It is believed that
the tigers will only attack people from behind. So for the past few years many workers in the
reserve have started wearing masks depicting a human face on the back of their heads. While
many area residents remain skeptical, no worker wearing one of these masks has yet been
attacked by a tiger. Which of the statements below, if true, would best support the argument of those who advocate the use of the mask?

(A) Many workers in the nature reserve who do not wear the masks have been attacked recently by tigers.

(B) Workers in other nature reserves who wear similar masks have not been attacked recently by tigers.

(C) No tigers have been spotted on the nature reserve in recent years.

(D) Many of the workers who wear the masks also sing while they work in order to
frighten away any tigers in the area.

(E) The tigers have often been observed attacking small deer from in front rather than from behind.

OA A
