Q: Question: "What counter-intuitively needs to use crop diversity?" Context: "Interspecific crop diversity is, in part, responsible for offering variety in what we eat. Intraspecific diversity, the variety of alleles within a single species, also offers us choice in our diets. If a crop fails in a monoculture, we rely on agricultural diversity to replant the land with something new. If a wheat crop is destroyed by a pest we may plant a hardier variety of wheat the next year, relying on intraspecific diversity. We may forgo wheat production in that area and plant a different species altogether, relying on interspecific diversity. Even an agricultural society which primarily grows monocultures, relies on biodiversity at some point." Answer:
A: monocultures

Q: Question: "what is the second type of establishment mentioned?" Context: "In Europe, it is the provision of accommodation, if anything, that now distinguishes inns from taverns, alehouses and pubs. The latter tend to provide alcohol (and, in the UK, soft drinks and often food), but less commonly accommodation. Inns tend to be older and grander establishments: historically they provided not only food and lodging, but also stabling and fodder for the traveller's horse(s) and on some roads fresh horses for the mail coach. Famous London inns include The George, Southwark and The Tabard. There is however no longer a formal distinction between an inn and other kinds of establishment. Many pubs use "Inn" in their name, either because they are long established former coaching inns, or to summon up a particular kind of image, or in many cases simply as a pun on the word "in", as in "The Welcome Inn", the name of many pubs in Scotland." Answer:
A: taverns

Q: Question: "Institutes of technology were developed in the 1950s to help grow a?" Context: "Institutes of technology in Venezuela were developed in the 1950s as an option for post-secondary education in technical and scientific courses, after the polytechnic French concepts. At that time, technical education was considered essential for the development of a sound middle class economy." Answer:
A: sound middle class economy

Q: Question: "What theory is crucial for quantum dot display?" Context: "The structure of QD-LEDs used for the electrical-excitation scheme is similar to basic design of OLEDs. A layer of quantum dots is sandwiched between layers of electron-transporting and hole-transporting materials. An applied electric field causes electrons and holes to move into the quantum dot layer and recombine forming an exciton that excites a QD. This scheme is commonly studied for quantum dot display. The tunability of emission wavelengths and narrow bandwidth is also beneficial as excitation sources for fluorescence imaging. Fluorescence near-field scanning optical microscopy (NSOM) utilizing an integrated QD-LED has been demonstrated." Answer:
A:
electrical-excitation scheme
