Problem: Text: The northern cardinal is found in residential areas throughout its range. Backyard birders attract it using feeders containing seeds, particularly sunflower seeds and safflower seeds. Although some controversy surrounds bird feeding, an increase in backyard feeding by humans has generally been beneficial to this species. It is listed as a species of least concern by the IUCN Red List, with an estimated global range of 5,800,000 km (2,200,000 sq mi) and a global population of some 100 million. Populations appear to remain stable and not threatened to reach the threshold of inclusion as a threatened species, which requires a decline of more than 30% in ten years or three generations. It was once prized as a pet due to its bright color and distinctive song. In the United States, this species receives special legal protection under the Migratory Bird Treaty Act of 1918, which also banned their sale as cage birds. It is also protected by the Convention for the Protection of Migratory Birds in Canada. It is illegal to take, kill, or possess northern cardinals, and violation of the law is punishable by a fine of up to US $15,000 and imprisonment of up to six months.

Problem: Text: In blood, the serum (/srm/) is the component that is neither a blood cell (serum does not contain white or red blood cells) nor a clotting factor; it is the blood plasma not including the fibrinogens. Serum includes all proteins not used in blood clotting (coagulation) and all the electrolytes, antibodies, antigens, hormones, and any exogenous substances (e.g., drugs and microorganisms).

Problem: Text: An ice rink (or ice skating rink) is a frozen body of water and/or hardened chemicals where people can ice skate or play winter sports. Besides recreational ice skating, some of its uses include ice hockey, bandy, rink bandy, ringette, broomball, speed skating, figure skating, ice stock sport and curling as well as exhibitions, contests and ice shows. There are two types of rinks in prevalent use today: natural, where freezing occurs from cold ambient temperatures, and artificial (or mechanically frozen), where a coolant produces cold temperatures in the surface below the water, causing the water to freeze. There are also synthetic ice rinks where skating surfaces are made out of plastics.

Question: is it cold in the ice skating rink?

OPTIONS:
- no
- yes
A:
yes
