[EX Q]: passage: Bull sharks can thrive in both salt and fresh water and can travel far up rivers. They have been known to travel up the Mississippi River as far as Alton, Illinois, about 700 miles (1100 km) from the ocean. However, few freshwater human-shark interactions have been recorded. Larger-sized bull sharks are probably responsible for the majority of near-shore shark attacks, including many bites attributed to other species.
 question: are there any sharks in the mississippi river?
[EX A]: Yes

[EX Q]: passage: A drinking straw or drinking tube is a small pipe that allows its user to more conveniently consume a beverage. A thin tube of paper, plastic (such as polypropylene and polystyrene), or other material is used by placing one end in the mouth and the other in the beverage. A combination of muscular action of the tongue and cheeks reduces air pressure in the mouth and above the liquid in the straw, whereupon atmospheric pressure forces the beverage through the straw. Drinking straws can be straight or have an angle-adjustable bellows segment.
 question: did straws used to be made of paper?
[EX A]:
Yes
