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

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.

Who lost their majority in parliament?, Context: The 1923 general election was fought on the Conservatives' protectionist proposals but, although they got the most votes and remained the largest party, they lost their majority in parliament, necessitating the formation of a government supporting free trade. Thus, with the acquiescence of Asquith's Liberals, Ramsay MacDonald became the first ever Labour Prime Minister in January 1924, forming the first Labour government, despite Labour only having 191 MPs (less than a third of the House of Commons).

German and French are examples of what system of agreed upon human communication?, Context: In some languages, such as English, aspiration is allophonic. Stops are distinguished primarily by voicing, and voiceless stops are sometimes aspirated, while voiced stops are usually unaspirated.
