Which of the following statements about the first scuba diving suit is true
a. it weighed about 100 pounds
b. it was made in the 1950s
c. it weighed about 50 pounds
d. it was made in the 1870s

I'm pretty sure the answer is b. it was made in 1950s. A and b are both false because true scuba diving gear weighs more than 100 pounds. I think the answer might be b. because the scuba diving suit was made and patented in 1951 by a holding company called Pirelli.

B it was made in the 1950s
