In this task, you're given a question, a context passage, and four options which are terms from the passage. After reading a passage, you will get a brief understanding of the terms. Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.

Input: Consider Input: Question: What is the name of the person who was most recently given the award Melvill received in 1843? Passage:Melvill van Carnbee traced his descent from an old Scottish family, originally, it is said, of Hungarian extraction. Destined for the navy, in which his grandfather Pieter Melvill van Carnbee (1743-1810) had been admiral, he had a taste for hydrography and cartography as a student in the college of Medemblik, and he showed his capacity as a surveyor on his first voyage to the Dutch Indies, in 1835. In 1839, he was again in the East, and was attached to the hydrographical bureau at Batavia. With the assistance of documents collected by the old East India Company, he completed a map of Java in five sheets, accompanied by sailing directions, in Amsterdam, in 1842. He remained in the East until 1845, collecting materials for a chart of the waters between Sumatra and Borneo, which was two sheets that were published in 1845 and 1846. In his absence, Melvill received the decoration of the Netherlands Lion in 1843, and that of the Legion of Honour in 1849.

Input: Consider Input: Question: Which former Digital Equipment Corporation who worked for Microsoft is the oldest? Passage:In November 1988, a new development team within Microsoft (which included former Digital Equipment Corporation developers Dave Cutler and Mark Lucovsky) began work on a revamped version of IBM and Microsoft's OS/2 operating system known as "NT OS/2". NT OS/2 was intended to be a secure, multi-user operating system with POSIX compatibility and a modular, portable kernel with preemptive multitasking and support for multiple processor architectures. However, following the successful release of Windows 3.0, the NT development team decided to rework the project to use an extended 32-bit port of the Windows API known as Win32 instead of those of OS/2. Win32 maintained a similar structure to the Windows APIs (allowing existing Windows applications to easily be ported to the platform), but also supported the capabilities of the existing NT kernel. Following its approval by Microsoft's staff, development continued on what was now Windows NT, the first 32-bit version of Windows. However, IBM objected to the changes, and ultimately continued OS/2 development on its own.
 Links: a. Software portability b. 32-bit c. 32-bit d. Dave Cutler

Output: d


Input: Consider Input: Question: Which location sits higher above sea level, the modern capital of Armenia or the location where the fortress was found in 782? Passage:The name Armenia was given to the country by the surrounding states, and it is traditionally derived from Armenak or Aram (the great-grandson of Haik's great-grandson, and another leader who is, according to Armenian tradition, the ancestor of all Armenians). In the Bronze Age, several states flourished in the area of Greater Armenia, including the Hittite Empire (at the height of its power), Mitanni (South-Western historical Armenia), and Hayasa-Azzi (1600–1200 BC). Soon after the Hayasa-Azzi were the Nairi (1400–1000 BC) and the Kingdom of Urartu (1000–600 BC), who successively established their sovereignty over the Armenian Highland. Each of the aforementioned nations and tribes participated in the ethnogenesis of the Armenian people. Yerevan, the modern capital of Armenia, dates back to the 8th century BC, with the founding of the fortress of Erebuni in 782 BC by King Argishti I at the western extreme of the Ararat plain. Erebuni has been described as "designed as a great administrative and religious centre, a fully royal capital."
