[Q]: Extract the answer to the question from the following context. Question: What would require specialty machinery? Context: As an electro-magnetic wave travels through the different parts of the antenna system (radio, feed line, antenna, free space) it may encounter differences in impedance (E/H, V/I, etc.). At each interface, depending on the impedance match, some fraction of the wave's energy will reflect back to the source, forming a standing wave in the feed line. The ratio of maximum power to minimum power in the wave can be measured and is called the standing wave ratio (SWR). A SWR of 1:1 is ideal. A SWR of 1.5:1 is considered to be marginally acceptable in low power applications where power loss is more critical, although an SWR as high as 6:1 may still be usable with the right equipment. Minimizing impedance differences at each interface (impedance matching) will reduce SWR and maximize power transfer through each part of the antenna system.

[A]: SWR as high as 6:1 may still be usable with the right equipment


[Q]: Extract the answer to the question from the following context. Question: Is the theory based more on subjective thought, quantitative measurements, or epistemic considerations? Context: Upon this basis, along with that of the logical content of assertions (where logical content is inversely proportional to probability), Popper went on to develop his important notion of verisimilitude or "truthlikeness". The intuitive idea behind verisimilitude is that the assertions or hypotheses of scientific theories can be objectively measured with respect to the amount of truth and falsity that they imply. And, in this way, one theory can be evaluated as more or less true than another on a quantitative basis which, Popper emphasises forcefully, has nothing to do with "subjective probabilities" or other merely "epistemic" considerations.

[A]: quantitative


[Q]: Extract the answer to the question from the following context. Question: Which reason is mentioned in the text that caused Kerry and John to pass a resolution regarding Vietnam? Context: Kerry chaired the Senate Select Committee on POW/MIA Affairs from 1991 to 1993. The committee's report, which Kerry endorsed, stated there was "no compelling evidence that proves that any American remains alive in captivity in Southeast Asia." In 1994 the Senate passed a resolution, sponsored by Kerry and fellow Vietnam veteran John McCain, that called for an end to the existing trade embargo against Vietnam; it was intended to pave the way for normalization. In 1995, President Bill Clinton normalized diplomatic relations with the country of Vietnam.

[A]: to pave the way for normalization


[Q]: Extract the answer to the question from the following context. Question: What do witnesses do instead of the meeting they used to have? Context: Meetings for worship and study are held at Kingdom Halls, which are typically functional in character, and do not contain religious symbols. Witnesses are assigned to a congregation in whose "territory" they usually reside and attend weekly services they refer to as "meetings" as scheduled by congregation elders. The meetings are largely devoted to study of Watch Tower Society literature and the Bible. The format of the meetings is established by the religion's headquarters, and the subject matter for most meetings is the same worldwide. Congregations meet for two sessions each week comprising five distinct meetings that total about three-and-a-half hours, typically gathering mid-week (three meetings) and on the weekend (two meetings). Prior to 2009, congregations met three times each week; these meetings were condensed, with the intention that members dedicate an evening for "family worship". Gatherings are opened and closed with kingdom songs (hymns) and brief prayers. Twice each year, Witnesses from a number of congregations that form a "circuit" gather for a one-day assembly. Larger groups of congregations meet once a year for a three-day "regional convention", usually at rented stadiums or auditoriums. Their most important and solemn event is the commemoration of the "Lord's Evening Meal", or "Memorial of Christ's Death" on the date of the Jewish Passover.
