Question: Mexico City remains the only Latin American city to host the Olympic Games, having held the Summer Olympics in 1968, winning bids against Buenos Aires, Lyon and Detroit. (This too will change thanks to Rio, 2016 Summer Games host). The city hosted the 1955 and 1975 Pan American Games, the last after Santiago and Sao Paulo withdrew. The ICF Flatwater Racing World Championships were hosted here in 1974 and 1994. Lucha libre is a Mexican style of wrestling, and is one of the more popular sports throughout the country. The main venues in the city are Arena Mexico and Arena Coliseo.
Is there an answer to this question: What year did Mexico City first host the Pan America games?

Answer: 1955

Question: Many assembled PCBs are static sensitive, and therefore must be placed in antistatic bags during transport. When handling these boards, the user must be grounded (earthed). Improper handling techniques might transmit an accumulated static charge through the board, damaging or destroying components. Even bare boards are sometimes static sensitive. Traces have become so fine that it's quite possible to blow an etch off the board (or change its characteristics) with a static charge. This is especially true on non-traditional PCBs such as MCMs and microwave PCBs.
Is there an answer to this question: Proper handling techniques might transmit what?

Answer: unanswerable

Question: A sample rate of 44.1 kHz is almost always used, because this is also used for CD audio, the main source used for creating MP3 files. A greater variety of bit rates are used on the Internet. The rate of 128 kbit/s is commonly used, at a compression ratio of 11:1, offering adequate audio quality in a relatively small space. As Internet bandwidth availability and hard drive sizes have increased, higher bit rates up to 320 kbit/s are widespread.

Answer: CD audio

Question: Title I of the U.S. DMCA, the WIPO Copyright and Performances and Phonograms Treaties Implementation Act has provisions that prevent persons from "circumvent[ing] a technological measure that effectively controls access to a work". Thus if a distributor of copyrighted works has some kind of software, dongle or password access device installed in instances of the work, any attempt to bypass such a copy protection scheme may be actionable though the US Copyright Office is currently reviewing anticircumvention rulemaking under DMCA anticircumvention exemptions that have been in place under the DMCA include those in software designed to filter websites that are generally seen to be inefficient (child safety and public library website filtering software) and the circumvention of copy protection mechanisms that have malfunctioned, have caused the instance of the work to become inoperable or which are no longer supported by their manufacturers.
