question:
Passage: For instance, a phased array consists of two or more simple antennas which are connected together through an electrical network. This often involves a number of parallel dipole antennas with a certain spacing. Depending on the relative phase introduced by the network, the same combination of dipole antennas can operate as a "broadside array" (directional normal to a line connecting the elements) or as an "end-fire array" (directional along the line connecting the elements). Antenna arrays may employ any basic (omnidirectional or weakly directional) antenna type, such as dipole, loop or slot antennas. These elements are often identical. Question: How many antenna would make up a phased array?
answer:
two or more


question:
Passage: Reptiles such as adders and vipers live up to the snow line; because they cannot bear the cold temperatures they hibernate underground and soak up the warmth on rocky ledges. The high-altitude Alpine salamanders have adapted to living above the snow line by giving birth to fully developed young rather than laying eggs. Brown trout can be found in the streams up to the snow line. Molluscs such as the wood snail live up the snow line. Popularly gathered as food, the snails are now protected. Question: Why do reptiles only live up to the snow line?
answer:
they cannot bear the cold temperatures


question:
Passage: On 7 April 1963, the country changed its official name to the Socialist Federal Republic of Yugoslavia. Reforms encouraged private enterprise and greatly relaxed restrictions on freedom of speech and religious expression. Tito subsequently went on a tour of the Americas. In Chile, two government ministers resigned over his visit to that country. In the autumn of 1960 Tito met President Dwight D. Eisenhower at the United Nations General Assembly meeting. Tito and Eisenhower discussed a range of issues from arms control to economic development. When Eisenhower remarked that Yugoslavia's neutralism was "neutral on his side", Tito replied that neutralism did not imply passivity but meant "not taking sides". Question: Who said that neutralism did not imply passivity but mean "not taking sides"?
answer:

Tito
