Input: Article: In addition to the use of sound for communication, a wide range of insects have evolved chemical means for communication. These chemicals, termed semiochemicals, are often derived from plant metabolites include those meant to attract, repel and provide other kinds of information. Pheromones, a type of semiochemical, are used for attracting mates of the opposite sex, for aggregating conspecific individuals of both sexes, for deterring other individuals from approaching, to mark a trail, and to trigger aggression in nearby individuals. Allomonea benefit their producer by the effect they have upon the receiver. Kairomones benefit their receiver instead of their producer. Synomones benefit the producer and the receiver. While some chemicals are targeted at individuals of the same species, others are used for communication across species. The use of scents is especially well known to have developed in social insects.:96105

Now answer this question: Insect chemicals are used to attract and what else?

Output: repel

Input: Article: The Central Intelligence Agency (CIA) is a quasi-independent agency of the United States Government. It appears to have multiple leadership. On the one hand its director is appointed by the president. It plays a significant role in providing the president with intelligence. On the other hand, Congress oversees its operations through a committee. The CIA was first formed under the National Security Act of 1947 from the army's Office of Strategic Services (OSS), which furnished both military intelligence and clandestine military operations to the army during the crisis of World War II. Many revisions and redefinitions have taken place since then. Although the name of the CIA reflects the original advised intent of Presidents Franklin D. Roosevelt and Harry S. Truman, the government's needs for strategic services have frustrated that intent from the beginning. The press received by the agency in countless articles, novels and other media have tended to create various popular myths; for example, that this agency replaced any intelligence effort other than that of the OSS, or that it contains the central intelligence capability of the United States. Strategic services are officially provided by some 17 agencies called the Intelligence Community. Army intelligence did not come to an end; in fact, all the branches of the Armed Forces retained their intelligence services. This community is currently under the leadership (in addition to all its other leadership) of the Office of the Director of National Intelligence.

Now answer this question: Who appoints the director of the CIA?

Output: the president

Input: Article: The fossil record suggests that the last few million years featured the greatest biodiversity in history. However, not all scientists support this view, since there is uncertainty as to how strongly the fossil record is biased by the greater availability and preservation of recent geologic sections. Some scientists believe that corrected for sampling artifacts, modern biodiversity may not be much different from biodiversity 300 million years ago., whereas others consider the fossil record reasonably reflective of the diversification of life. Estimates of the present global macroscopic species diversity vary from 2 million to 100 million, with a best estimate of somewhere near 9 million, the vast majority arthropods. Diversity appears to increase continually in the absence of natural selection.

Now answer this question: What appears increase continually in the absence of natural selection?

Output:
Diversity
