Input: Read this: There has been some concern over the potential adverse environmental and ecosystem effects caused by the influx of visitors. Some environmentalists and scientists have made a call for stricter regulations for ships and a tourism quota. The primary response by Antarctic Treaty Parties has been to develop, through their Committee for Environmental Protection and in partnership with IAATO, "site use guidelines" setting landing limits and closed or restricted zones on the more frequently visited sites. Antarctic sightseeing flights (which did not land) operated out of Australia and New Zealand until the fatal crash of Air New Zealand Flight 901 in 1979 on Mount Erebus, which killed all 257 aboard. Qantas resumed commercial overflights to Antarctica from Australia in the mid-1990s.
Question: Who resumed commercial overflights to Antarctica to Australia in 1990?

Input: Read this: It also includes the alternative 1440×1152 HDMAC scan format. (According to some reports, a mooted 750-line (720p) format (720 progressively scanned lines) was viewed by some at the ITU as an enhanced television format rather than a true HDTV format, and so was not included, although 1920×1080i and 1280×720p systems for a range of frame and field rates were defined by several US SMPTE standards.)
Question: What were 1920x1080i and 1280x720p defined by?

Input: Read this: In Singapore, madrasahs are private schools which are overseen by Majlis Ugama Islam Singapura (MUIS, English: Islamic Religious Council of Singapore). There are six Madrasahs in Singapore, catering to students from Primary 1 to Secondary 4. Four Madrasahs are coeducational and two are for girls. Students take a range of Islamic Studies subjects in addition to mainstream MOE curriculum subjects and sit for the PSLE and GCE 'O' Levels like their peers. In 2009, MUIS introduced the "Joint Madrasah System" (JMS), a joint collaboration of Madrasah Al-Irsyad Al-Islamiah primary school and secondary schools Madrasah Aljunied Al-Islamiah (offering the ukhrawi, or religious stream) and Madrasah Al-Arabiah Al-Islamiah (offering the academic stream). The JMS aims to introduce the International Baccalaureate (IB) programme into the Madrasah Al-Arabiah Al-Islamiah by 2019. Students attending a madrasah are required to wear the traditional Malay attire, including the songkok for boys and tudong for girls, in contrast to mainstream government schools which ban religious headgear as Singapore is officially a secular state. For students who wish to attend a mainstream school, they may opt to take classes on weekends at the madrasah instead of enrolling full-time.
Question: What year is it planned for IB programs to be in place at Madrasah Al-Arabiah Al-Islamiah?

Output: 2019
