Question: 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.

Answer: LEDs have also been used as a medium-quality voltage

Question: Which of the following is not a port linked to Palermo: Genoa, Naples or marina?, Context: The port of Palermo, founded by the Phoenicians over 2,700 years ago, is, together with the port of Messina, the main port of Sicily. From here ferries link Palermo to Cagliari, Genoa, Livorno, Naples, Tunis and other cities and carry a total of almost 2 million passengers annually. It is also an important port for cruise ships. Traffic includes also almost 5 million tonnes of cargo and 80.000 TEU yearly. The port also has links to minor sicilian islands such as Ustica and the Aeolian Islands (via Cefalu in summer). Inside the Port of Palermo there is a section known as "tourist marina" for sailing yachts and catamarans.

Answer: marina

Question: Which group of people had killed a two-digit number of Palestinians by April 30th, 2008?, Context: After the collapse of the talks and a controversial visit by Likud leader Ariel Sharon to the Temple Mount, the Second Intifada began. Some commentators contend that the uprising was pre-planned by Yasser Arafat due to the collapse of peace talks. Sharon became prime minister in a 2001 special election. During his tenure, Sharon carried out his plan to unilaterally withdraw from the Gaza Strip and also spearheaded the construction of the Israeli West Bank barrier, ending the Intifada. By this time 1,100 Israelis had been killed, mostly in suicide bombings. The Palestinian fatalities, by 30 April 2008, reached 4,745 killed by Israeli security forces, 44 killed by Israeli civilians, and 577 killed by Palestinians.

Answer:
Israeli civilians
