Input: Article: Hayek had a long-standing and close friendship with philosopher of science Karl Popper, also from Vienna. In a letter to Hayek in 1944, Popper stated, "I think I have learnt more from you than from any other living thinker, except perhaps Alfred Tarski." (See Hacohen, 2000). Popper dedicated his Conjectures and Refutations to Hayek. For his part, Hayek dedicated a collection of papers, Studies in Philosophy, Politics, and Economics, to Popper and, in 1982, said that "ever since his Logik der Forschung first came out in 1934, I have been a complete adherent to his general theory of methodology". Popper also participated in the inaugural meeting of the Mont Pelerin Society. Their friendship and mutual admiration, however, do not change the fact that there are important differences between their ideas.

Now answer this question: Hayek dedicated many of his papers to Popper based on a dedication Popper made to him in which of his work?

Output: Conjectures and Refutations

Article: 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.

Question: What type of a society primarily grows monocultures?
Ans: agricultural society

Here is a question about this article: The standard connectors were deliberately intended to enforce the directed topology of a USB network: Type-A receptacles on host devices that supply power and Type-B receptacles on target devices that draw power. This prevents users from accidentally connecting two USB power supplies to each other, which could lead to short circuits and dangerously high currents, circuit failures, or even fire. USB does not support cyclic networks and the standard connectors from incompatible USB devices are themselves incompatible.
What is the answer to this question: What do the receptacles prevent user from doing?
****
So... from accidentally connecting two USB power supplies to each other
