Article: Albert Einstein is known for his theories of special relativity and general relativity. He also made important contributions to statistical mechanics, especially his mathematical treatment of Brownian motion, his resolution of the paradox of specific heats, and his connection of fluctuations and dissipation. Despite his reservations about its interpretation, Einstein also made contributions to quantum mechanics and, indirectly, quantum field theory, primarily through his theoretical studies of the photon.

Question: What theory  did Einstein have reservations about?
Ans: quantum field theory


Article: Congress often writes legislation to restrain executive officials to the performance of their duties, as laid out by the laws Congress passes. In INS v. Chadha (1983), the Supreme Court decided (a) The prescription for legislative action in Art. I, § 1—requiring all legislative powers to be vested in a Congress consisting of a Senate and a House of Representatives—and § 7—requiring every bill passed by the House and Senate, before becoming law, to be presented to the president, and, if he disapproves, to be repassed by two-thirds of the Senate and House—represents the Framers' decision that the legislative power of the Federal Government be exercised in accord with a single, finely wrought and exhaustively considered procedure. This procedure is an integral part of the constitutional design for the separation of powers. Further rulings clarified the case; even both Houses acting together cannot override Executive vetos without a 2⁄3 majority. Legislation may always prescribe regulations governing executive officers.

Question: When was INS v Chadha tried before the Supreme Court?
Ans: 1983

The hilly Vagad region, home to the cities of Dungarpur and Banswara lies in southernmost Rajasthan, on the border with Gujarat and Madhya Pradesh. With the exception of Mount Abu, Vagad is the wettest region in Rajasthan, and the most heavily forested. North of Vagad lies the Mewar region, home to the cities of Udaipur and Chittaurgarh. The Hadoti region lies to the southeast, on the border with Madhya Pradesh. North of Hadoti and Mewar lies the Dhundhar region, home to the state capital of Jaipur. Mewat, the easternmost region of Rajasthan, borders Haryana and Uttar Pradesh. Eastern and southeastern Rajasthan is drained by the Banas and Chambal rivers, tributaries of the Ganges.

Question: What is the name of the ecoregion to the east and southeast of the Aravalli Range?
Ans: the Kathiarbar-Gir dry deciduous forests ecoregion
