[EX Q]: What is fundamental to the function of the airport that has yet to be obtained?, Context: The UK government has spent £250 million in the construction of the island's airport. Expected to be fully operational early 2016, it is expected to help the island towards self-sufficiency and encourage economic development, reducing dependence on British government aid. The airport is also expected to kick start the tourism industry, with up to 30,000 visitors expected annually. As of August, 2015 ticketing was postponed until an airline could be firmly designated.

[EX Q]: The second Multilingual European subset includes everything from which other Unicode subsets?, Context: Several subsets of Unicode are standardized: Microsoft Windows since Windows NT 4.0 supports WGL-4 with 652 characters, which is considered to support all contemporary European languages using the Latin, Greek, or Cyrillic script. Other standardized subsets of Unicode include the Multilingual European Subsets: MES-1 (Latin scripts only, 335 characters), MES-2 (Latin, Greek and Cyrillic 1062 characters) and MES-3A & MES-3B (two larger subsets, not shown here). Note that MES-2 includes every character in MES-1 and WGL-4.
[EX A]: MES-1 and WGL-4

[EX Q]: Use of condoms is a more effective than what other less effective method?, Context: Given the potential consequences, engaging in sexual behavior is somewhat risky, particularly for adolescents. Having unprotected sex, using poor birth control methods (e.g. withdrawal), having multiple sexual partners, and poor communication are some aspects of sexual behavior that increase individual and/or social risk. Some qualities of adolescents' lives that are often correlated with risky sexual behavior include higher rates of experienced abuse, lower rates of parental support and monitoring. Adolescence is also commonly a time of questioning sexuality and gender. This may involve intimate experimentation with people identifying as the same gender as well as with people of differing genders. Such exploratory sexual behavior can be seen as similar to other aspects of identity, including the exploration of vocational, social, and leisure identity, all of which involve some risk.
