Problem: Please answer a question about the following article about Yale University:
Yale seniors at graduation smash clay pipes underfoot to symbolize passage from their "bright college years," though in recent history the pipes have been replaced with "bubble pipes". ("Bright College Years," the University's alma mater, was penned in 1881 by Henry Durand, Class of 1881, to the tune of Die Wacht am Rhein.) Yale's student tour guides tell visitors that students consider it good luck to rub the toe of the statue of Theodore Dwight Woolsey on Old Campus. Actual students rarely do so. In the second half of the 20th century Bladderball, a campus-wide game played with a large inflatable ball, became a popular tradition but was banned by administration due to safety concerns. In spite of administration opposition, students revived the game in 2009, 2011, and 2014, but its future remains uncertain.
What do they destroy now instead of clay pipes?
A: bubble pipes

While LEDs have the advantage over fluorescent lamps that they do not contain mercury, they may contain other hazardous metals such as lead and arsenic. Regarding the toxicity of LEDs when treated as waste, a study published in 2011 stated: "According to federal standards, LEDs are not hazardous except for low-intensity red LEDs, which leached Pb [lead] at levels exceeding regulatory limits (186 mg/L; regulatory limit: 5). However, according to California regulations, excessive levels of copper (up to 3892 mg/kg; limit: 2500), lead (up to 8103 mg/kg; limit: 1000), nickel (up to 4797 mg/kg; limit: 2000), or silver (up to 721 mg/kg; limit: 500) render all except low-intensity yellow LEDs hazardous."

What substance does fluorescent lamps contain?
Answer: mercury

Problem: Czech distinguishes three gendersmasculine, feminine, and neuterand the masculine gender is subdivided into animate and inanimate. With few exceptions, feminine nouns in the nominative case end in -a, -e, or -ost; neuter nouns in -o, -e, or -i, and masculine nouns in a consonant. Adjectives agree in gender and animacy (for masculine nouns in the accusative or genitive singular and the nominative plural) with the nouns they modify. The main effect of gender in Czech is the difference in noun and adjective declension, but other effects include past-tense verb endings: for example, delal (he did, or made); delala (she did, or made) and delalo (it did, or made).
What is the main effect of gender in Czech?
The answer is the following: difference in noun and adjective declension

Hydrogen production technologies been a significant area of solar chemical research since the 1970s. Aside from electrolysis driven by photovoltaic or photochemical cells, several thermochemical processes have also been explored. One such route uses concentrators to split water into oxygen and hydrogen at high temperatures (2,3002,600 C or 4,2004,700 F). Another approach uses the heat from solar concentrators to drive the steam reformation of natural gas thereby increasing the overall hydrogen yield compared to conventional reforming methods. Thermochemical cycles characterized by the decomposition and regeneration of reactants present another avenue for hydrogen production. The Solzinc process under development at the Weizmann Institute uses a 1 MW solar furnace to decompose zinc oxide (ZnO) at temperatures above 1,200 C (2,200 F). This initial reaction produces pure zinc, which can subsequently be reacted with water to produce hydrogen.
What is the name of the process under development at the Weizmann Institute?
The Solzinc process

Input: The Legend of Zelda: Twilight Princess
The Legend of Zelda: Twilight Princess is an action-adventure game focused on combat, exploration, and item collection. It uses the basic control scheme introduced in Ocarina of Time, including context-sensitive action buttons and L-targeting (Z-targeting on the Wii), a system that allows the player to keep Link's view focused on an enemy or important object while moving and attacking. Link can walk, run, and attack, and will automatically jump when running off of or reaching for a ledge.[c] Link uses a sword and shield in combat, complemented with secondary weapons and items, including a bow and arrows, a boomerang, bombs, and the Clawshot (similar to the Hookshot introduced earlier in the The Legend of Zelda series).[d] While L-targeting, projectile-based weapons can be fired at a target without the need for manual aiming.[c]

What is Link's main weapon?
Output: sword

Problem: Please answer a question about the following article about British Empire:
Peace between England and the Netherlands in 1688 meant that the two countries entered the Nine Years' War as allies, but the conflictwaged in Europe and overseas between France, Spain and the Anglo-Dutch allianceleft the English a stronger colonial power than the Dutch, who were forced to devote a larger proportion of their military budget on the costly land war in Europe. The 18th century saw England (after 1707, Britain) rise to be the world's dominant colonial power, and France becoming its main rival on the imperial stage.
In which century did Britain become the world's dominant colonial power?
A:
18th
