Problem: Question: "What might indicate that an animal is less intelligent than others?"  Context: "In intelligent mammals, such as primates, the cerebrum is larger relative to the rest of the brain. Intelligence itself is not easy to define, but indications of intelligence include the ability to learn, matched with behavioral flexibility. Rats, for example, are considered to be highly intelligent, as they can learn and perform new tasks, an ability that may be important when they first colonize a fresh habitat. In some mammals, food gathering appears to be related to intelligence: a deer feeding on plants has a brain smaller than a cat, which must think to outwit its prey."  Answer:

A: brain smaller

Problem: Question: "Why was the former president of the EMI chosen?"  Context: "The first President of the Bank was Wim Duisenberg, the former president of the Dutch central bank and the European Monetary Institute. While Duisenberg had been the head of the EMI (taking over from Alexandre Lamfalussy of Belgium) just before the ECB came into existence, the French government wanted Jean-Claude Trichet, former head of the French central bank, to be the ECB's first president. The French argued that since the ECB was to be located in Germany, its president should be French. This was opposed by the German, Dutch and Belgian governments who saw Duisenberg as a guarantor of a strong euro. Tensions were abated by a gentleman's agreement in which Duisenberg would stand down before the end of his mandate, to be replaced by Trichet."  Answer:

A: German, Dutch and Belgian governments who saw Duisenberg as a guarantor of a strong euro
