In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

[Q]: How do you know that the main topic of discussion is not overall considered high power?, Context: LEDs have also been used as a medium-quality voltage reference in electronic circuits. The forward voltage drop (e.g. about 1.7 V for a normal red LED) can be used instead of a Zener diode in low-voltage regulators. Red LEDs have the flattest I/V curve above the knee. Nitride-based LEDs have a fairly steep I/V curve and are useless for this purpose. Although LED forward voltage is far more current-dependent than a Zener diode, Zener diodes with breakdown voltages below 3 V are not widely available.
[A]: LEDs have also been used as a medium-quality voltage


[Q]: What students is City of Bath School limited to?, Context: Some of the county's secondary schools have specialist school status. Some schools have sixth forms and others transfer their sixth formers to colleges. Several schools can trace their origins back many years, such as The Blue School in Wells and Richard Huish College in Taunton. Others have changed their names over the years such as Beechen Cliff School which was started in 1905 as the City of Bath Boys' School and changed to its present name in 1972 when the grammar school was amalgamated with a local secondary modern school, to form a comprehensive school. Many others were established and built since the Second World War. In 2006, 5,900 pupils in Somerset sat GCSE examinations, with 44.5% achieving 5 grades A-C including English and Maths (compared to 45.8% for England).
[A]: Boys


[Q]: Which of the following does not have executive power, the President or two-thirds of the Senators?, Context: In the United States, the term "treaty" has a different, more restricted legal sense than exists in international law. United States law distinguishes what it calls treaties from executive agreement, congressional-executive agreements, and sole executive agreements. All four classes are equally treaties under international law; they are distinct only from the perspective of internal American law. The distinctions are primarily concerning their method of approval. Whereas treaties require advice and consent by two-thirds of the Senators present, sole executive agreements may be executed by the President acting alone. Some treaties grant the President the authority to fill in the gaps with executive agreements, rather than additional treaties or protocols. And finally, congressional-executive agreements require majority approval by both the House and the Senate, either before or after the treaty is signed by the President.
[A]:
two-thirds of the Senators
