History

The border disputes between the US and Mexico were initially addressed by the Treaty of Guadalupe Hidalgo in 1848, which established the international boundary after the Mexican-American War. However, some disputes persisted, notably the Chamizal dispute near El Paso, which was resolved by the Chamizal Convention in 1963. The final major settlement of pending boundary differences occurred with the Boundary Treaty of 1970, which became effective in 1972. The International Boundary and Water Commission, established in 1889, implemented these treaties and adopted further agreements, including a 1980 amendment clarifying water allocation and boundary provisions. Thus, 1980 marks the date of the last significant formal resolution of border disputes, making option D (1980) the most accurate answer among the choices provided.

The Battle of Halani was fought in 1748 between the Kalhora and Talpur dynasties in Sindh. Therefore, option B (1748) is the correct answer.

Zahir-ud-din Muhammad Babur, the founder of the Mughal Empire in India, died on 26 December 1530. This date is well documented in historical records.

Kalim-Allah Shah, also known as Kalimullah Shah, was the last ruler of the Bahmani Sultanate, and he died in 1537, marking the end of the empire.

Qutub-ud-din Aibak died in October 1208. This is a well-documented historical fact, making option A the correct answer.

Bahlul Khan Lodhi was the founder of the Lodhi dynasty in India, ruling from 1451 to 1489. Ibrahim Lodhi was his grandson and the last ruler of the dynasty. Therefore, option B is correct.

William Hawkins was an English sea captain and envoy who was honored by Mughal Emperor Jahangir with the title of Khan, recognizing his diplomatic efforts. The other options were either not Englishmen or not known to have received such a title from Jahangir.

Genghis Khan did not die in battle against the Western Xia Dynasty; he died in 1227, but the exact cause is uncertain and not confirmed as battle-related. Therefore, none of the given years correctly describe his death in battle against Western Xia.

The Republican Party of the USA was founded in the 1850s by anti-slavery activists and modernizers. It does not have a single founder. None of the options given (Alexander Hamilton, Franklin Roosevelt, George Washington, Thomas Jefferson) were founders of the Republican Party. However, all these figures lived before the party's founding except Franklin Roosevelt, who was a Democrat. Alexander Hamilton was a Federalist and died long before the Republican Party was founded. George Washington and Thomas Jefferson were founding fathers of the United States but not founders of the Republican Party. Since none of the options are correct, the question is flawed. The Republican Party was founded by a coalition of anti-slavery activists, not by any of these individuals. Therefore, the question should be corrected to reflect that no single founder exists and none of the options are correct. If forced to choose the closest related figure ideologically, Thomas Jefferson is sometimes associated with the early Republican ideals (Democratic-Republican Party), but that is not the same as the modern Republican Party founded in the 1850s. Hence, the question and options are factually incorrect as stated.

Richard Nixon is the only U.S. President who resigned from office, doing so in 1974 due to the Watergate scandal. Abraham Lincoln and Jimmy Carter did not resign, and 'none of these' is incorrect.
