Question: Read this and answer the question

James Rassmann, a Green Beret advisor who was aboard Kerry's PCF-94, was knocked overboard when, according to witnesses and the documentation of the event, a mine or rocket exploded close to the boat. According to the documentation for the event, Kerry's arm was injured when he was thrown against a bulkhead during the explosion. PCF 94 returned to the scene and Kerry rescued Rassmann who was receiving sniper fire from the water. Kerry received the Bronze Star Medal with Combat "V" for "heroic achievement", for his actions during this incident; he also received his third Purple Heart.

What boat was Rassmann on?
Answer: PCF-94


Problem: Sugar, starch, cotton, linen, hemp, some types of rope, wood and particle boards, papyrus and paper, vegetable oils, wax, and natural rubber are examples of commercially important materials made from plant tissues or their secondary products. Charcoal, a pure form of carbon made by pyrolysis of wood, has a long history as a metal-smelting fuel, as a filter material and adsorbent and as an artist's material and is one of the three ingredients of gunpowder. Cellulose, the world's most abundant organic polymer, can be converted into energy, fuels, materials and chemical feedstock. Products made from cellulose include rayon and cellophane, wallpaper paste, biobutanol and gun cotton. Sugarcane, rapeseed and soy are some of the plants with a highly fermentable sugar or oil content that are used as sources of biofuels, important alternatives to fossil fuels, such as biodiesel.
Rayon comes from what plant product?
The answer is the following: cellulose


The Umayyad Caliphate (Arabic: الخلافة الأموية‎, trans. Al-Khilāfat al-ʾumawiyya) was the second of the four major Islamic caliphates established after the death of Muhammad. This caliphate was centered on the Umayyad dynasty (Arabic: الأمويون‎, al-ʾUmawiyyūn, or بنو أمية, Banū ʾUmayya, "Sons of Umayya"), hailing from Mecca. The Umayyad family had first come to power under the third caliph, Uthman ibn Affan (r. 644–656), but the Umayyad regime was founded by Muawiya ibn Abi Sufyan, long-time governor of Syria, after the end of the First Muslim Civil War in 661 CE/41 AH. Syria remained the Umayyads' main power base thereafter, and Damascus was their capital. The Umayyads continued the Muslim conquests, incorporating the Caucasus, Transoxiana, Sindh, the Maghreb and the Iberian Peninsula (Al-Andalus) into the Muslim world. At its greatest extent, the Umayyad Caliphate covered 15 million km2 (5.79 million square miles), making it the largest empire (in terms of area - not in terms of population) the world had yet seen, and the fifth largest ever to exist.
How many million square miles was the Umayyad caliphate at its largest size?
5.79


Input: Electric motor
Perhaps the first electric motors were simple electrostatic devices created by the Scottish monk Andrew Gordon in the 1740s. The theoretical principle behind production of mechanical force by the interactions of an electric current and a magnetic field, Ampère's force law, was discovered later by André-Marie Ampère in 1820. The conversion of electrical energy into mechanical energy by electromagnetic means was demonstrated by the British scientist Michael Faraday in 1821. A free-hanging wire was dipped into a pool of mercury, on which a permanent magnet (PM) was placed. When a current was passed through the wire, the wire rotated around the magnet, showing that the current gave rise to a close circular magnetic field around the wire. This motor is often demonstrated in physics experiments, brine substituting for toxic mercury. Though Barlow's wheel was an early refinement to this Faraday demonstration, these and similar homopolar motors were to remain unsuited to practical application until late in the century.

Who discovered the principles of magnetic and electric interactions?
Output: André-Marie Ampère


Input: Article: Kuaiji Commandery was the initial power base for Xiang Liang and Xiang Yu's rebellion against the Qin Empire which initially succeeded in restoring the kingdom of Chu but eventually fell to the Han. Under the Later Han, control of the area returned to the settlement below Mount Kuaiji but authority over the Minyue hinterland was nominal at best and its Yue inhabitants largely retained their own political and social structures.

Now answer this question: Who led a rebellion with Xiang Liang against the Qin Empire?

Output: Xiang Yu


Problem: In 1827, soon after the death of Chopin's youngest sister Emilia, the family moved from the Warsaw University building, adjacent to the Kazimierz Palace, to lodgings just across the street from the university, in the south annex of the Krasiński Palace on Krakowskie Przedmieście,[n 5] where Chopin lived until he left Warsaw in 1830.[n 6] Here his parents continued running their boarding house for male students; the Chopin Family Parlour (Salonik Chopinów) became a museum in the 20th century. In 1829 the artist Ambroży Mieroszewski executed a set of portraits of Chopin family members, including the first known portrait of the composer.[n 7]
What artist made portraits of the Chopin family in 1829?
The answer is the following:
Ambroży Mieroszewski
