Paragraph comprehension

The Women's Flying Training Detachment was the brainchild of Jacqueline Cochran, the famous flyer. Because of the overwhelming demand for qualified men to fly in combat during World War II, she was able to persuade the Army to train women pilots to ferry military aircraft from manufacturers to embarkation points for later shipment overseas.

The author implies that the primary motivation for establishing a training program for women pilots during World War II was the

unavailability of qualified male pilots.

Riding the mail plane is a low-budget way to visit America's largest national park -- Wrangell-St. Elias --13 million acres of scenic beauty. Copper first drew prospectors to this part of Alaska. From 1911 to 1938, the Kennicott mine produced 200 million tons of it. Now a mecca for tourists, the town of Kennicott was abandoned to the ghosts when the copper ran out.

According to the passage, which of the following illustrates the correct sequence of events?

copper drew prospectors, tourist attraction, copper ran out, town abandoned

In the formula , if then C = 35 F =?

95

C = 5/9(F - 32)

C = 35

35 = 5/9(F-32)
