Question: Which dog breed is taller, the Chihuahua or the Irish Wolfhound?, Context: Most breeds of dog are at most a few hundred years old, having been artificially selected for particular morphologies and behaviors by people for specific functional roles. Through this selective breeding, the dog has developed into hundreds of varied breeds, and shows more behavioral and morphological variation than any other land mammal. For example, height measured to the withers ranges from 15.2 centimetres (6.0 in) in the Chihuahua to about 76 cm (30 in) in the Irish Wolfhound; color varies from white through grays (usually called "blue") to black, and browns from light (tan) to dark ("red" or "chocolate") in a wide variation of patterns; coats can be short or long, coarse-haired to wool-like, straight, curly, or smooth. It is common for most breeds to shed this coat.

Answer: Irish Wolfhound


Question: What did Kerry later run for?, Context: The junior U.S. Senator from Massachusetts, Paul Tsongas, announced in 1984 that he would be stepping down for health reasons. Kerry ran, and as in his 1982 race for Lieutenant Governor, he did not receive the endorsement of the party regulars at the state Democratic convention. Congressman James Shannon, a favorite of House Speaker Tip O'Neill, was the early favorite to win the nomination, and he "won broad establishment support and led in early polling." Again as in 1982, however, Kerry prevailed in a close primary.

Answer: Senator
