Input: Read this: Department stores today have sections that sell the following: clothing, furniture, home appliances, toys, cosmetics, gardening, toiletries, sporting goods, do it yourself, paint, and hardware and additionally select other lines of products such as food, books, jewelry, electronics, stationery, photographic equipment, baby products, and products for pets. Customers check out near the front of the store or, alternatively, at sales counters within each department. Some are part of a retail chain of many stores, while others may be independent retailers. In the 1970s, they came under heavy pressure from discounters. Since 2010, they have come under even heavier pressure from online stores such as Amazon.
Question: Who started influencing department stores in the 1970's? 

Output: discounters


Input: Read this: Problems with the 10NES lockout chip frequently resulted in the console's most infamous problem: the blinking red power light, in which the system appears to turn itself on and off repeatedly because the 10NES would reset the console once per second. The lockout chip required constant communication with the chip in the game to work. Dirty, aging and bent connectors would often disrupt the communication, resulting in the blink effect. Alternatively, the console would turn on but only show a solid white, gray, or green screen. Users attempted to solve this problem by blowing air onto the cartridge connectors, inserting the cartridge just far enough to get the ZIF to lower, licking the edge connector, slapping the side of the system after inserting a cartridge, shifting the cartridge from side to side after insertion, pushing the ZIF up and down repeatedly, holding the ZIF down lower than it should have been, and cleaning the connectors with alcohol. These attempted solutions often became notable in their own right and are often remembered alongside the NES. Many of the most frequent attempts to fix this problem instead ran the risk of damaging the cartridge and/or system.[citation needed] In 1989, Nintendo released an official NES Cleaning Kit to help users clean malfunctioning cartridges and consoles.
Question:  What didn't disrupt the communication as well?

Output: unanswerable


Input: Read this: The absence of a formal mechanism within the Conservative Party for choosing a leader meant that, following Eden's resignation, it fell to the Queen to decide whom to commission to form a government. Eden recommended that she consult Lord Salisbury, the Lord President of the Council. Lord Salisbury and Lord Kilmuir, the Lord Chancellor, consulted the British Cabinet, Winston Churchill, and the Chairman of the backbench 1922 Committee, resulting in the Queen appointing their recommended candidate: Harold Macmillan.
Question: In what year was Lord Kilmuir born?

Output: unanswerable


Input: Read this: When a molten metal is mixed with another substance, there are two mechanisms that can cause an alloy to form, called atom exchange and the interstitial mechanism. The relative size of each element in the mix plays a primary role in determining which mechanism will occur. When the atoms are relatively similar in size, the atom exchange method usually happens, where some of the atoms composing the metallic crystals are substituted with atoms of the other constituent. This is called a substitutional alloy. Examples of substitutional alloys include bronze and brass, in which some of the copper atoms are substituted with either tin or zinc atoms. With the interstitial mechanism, one atom is usually much smaller than the other, so cannot successfully replace an atom in the crystals of the base metal. The smaller atoms become trapped in the spaces between the atoms in the crystal matrix, called the interstices. This is referred to as an interstitial alloy. Steel is an example of an interstitial alloy, because the very small carbon atoms fit into interstices of the iron matrix. Stainless steel is an example of a combination of interstitial and substitutional alloys, because the carbon atoms fit into the interstices, but some of the iron atoms are replaced with nickel and chromium atoms.
Question: What is formed when molten metal is separated from other substances?

Output:
unanswerable
