Input: Read this: 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.
Question: What is an example of a poor birth control method?

Output: withdrawal

Input: Read this: The ranging signals are based on the CDMA principle and have complex structure typical of Galileo or modernized GPS. Similar to the other GNSS, there will be two levels of positioning service: open and restricted (military). The public service shall be available globally to general users. When all the currently planned GNSS systems are deployed, the users will benefit from the use of a total constellation of 75+ satellites, which will significantly improve all the aspects of positioning, especially availability of the signals in so-called urban canyons. The general designer of the COMPASS navigation system is Sun Jiadong, who is also the general designer of its predecessor, the original BeiDou navigation system.
Question: Who designed the COMPASS international trade system? 

Output: unanswerable
