Input: Article: The first step toward Indian self-rule was the appointment of councillors to advise the British viceroy in 1861 and the first Indian was appointed in 1909. Provincial Councils with Indian members were also set up. The councillors' participation was subsequently widened into legislative councils. The British built a large British Indian Army, with the senior officers all British and many of the troops from small minority groups such as Gurkhas from Nepal and Sikhs. The civil service was increasingly filled with natives at the lower levels, with the British holding the more senior positions.

Now answer this question: What appointments were  the first step in Indian self-rule?

Output: councillors

Input: Article: Although provision is made in Title 10 of the United States Code for the Secretary of the Air Force to appoint warrant officers, the Air Force does not currently use warrant officer grades, and is the only one of the U.S. Armed Services not to do so. The Air Force inherited warrant officer ranks from the Army at its inception in 1947, but their place in the Air Force structure was never made clear.[citation needed] When the Congress authorized the creation of two new senior enlisted ranks in 1958, Air Force officials privately concluded that these two new "super grades" could fill all Air Force needs then performed at the warrant officer level, although this was not publicly acknowledged until years later.[citation needed] The Air Force stopped appointing warrant officers in 1959, the same year the first promotions were made to the new top enlisted grade, Chief Master Sergeant. Most of the existing Air Force warrant officers entered the commissioned officer ranks during the 1960s, but small numbers continued to exist in the warrant officer grades for the next 21 years.

Now answer this question: When did the USAF inherit warrant officer ranks from the Army?

Output: 1947

Input: Article: For vertebrates, the early stages of neural development are similar across all species. As the embryo transforms from a round blob of cells into a wormlike structure, a narrow strip of ectoderm running along the midline of the back is induced to become the neural plate, the precursor of the nervous system. The neural plate folds inward to form the neural groove, and then the lips that line the groove merge to enclose the neural tube, a hollow cord of cells with a fluid-filled ventricle at the center. At the front end, the ventricles and cord swell to form three vesicles that are the precursors of the forebrain, midbrain, and hindbrain. At the next stage, the forebrain splits into two vesicles called the telencephalon (which will contain the cerebral cortex, basal ganglia, and related structures) and the diencephalon (which will contain the thalamus and hypothalamus). At about the same time, the hindbrain splits into the metencephalon (which will contain the cerebellum and pons) and the myelencephalon (which will contain the medulla oblongata). Each of these areas contains proliferative zones where neurons and glial cells are generated; the resulting cells then migrate, sometimes for long distances, to their final positions.

Now answer this question: The forebrain splits during development into vesicles called what?

Output:
telencephalon (which will contain the cerebral cortex, basal ganglia, and related structures) and the diencephalon
