QUES: In 1983, the International Telecommunication Union's radio telecommunications sector (ITU-R) set up a working party (IWP11/6) with the aim of setting a single international HDTV standard. One of the thornier issues concerned a suitable frame/field refresh rate, the world already having split into two camps, 25/50 Hz and 30/60 Hz, largely due to the differences in mains frequency. The IWP11/6 working party considered many views and throughout the 1980s served to encourage development in a number of video digital processing areas, not least conversion between the two main frame/field rates using motion vectors, which led to further developments in other areas. While a comprehensive HDTV standard was not in the end established, agreement on the aspect ratio was achieved.

What was one of the issues with setting a single HDTV standard?
What is the answer?
ANS: a suitable frame/field refresh rate
QUES: In some countries anti-Masonry is often related to antisemitism and anti-Zionism. For example, In 1980, the Iraqi legal and penal code was changed by Saddam Hussein's ruling Ba'ath Party, making it a felony to "promote or acclaim Zionist principles, including Freemasonry, or who associate [themselves] with Zionist organisations". Professor Andrew Prescott of the University of Sheffield writes: "Since at least the time of the Protocols of the Elders of Zion, antisemitism has gone hand in hand with anti-masonry, so it is not surprising that allegations that 11 September was a Zionist plot have been accompanied by suggestions that the attacks were inspired by a masonic world order".

In some countries, anti-Masonry is related to what?
What is the answer?
ANS: antisemitism and anti-Zionism
QUES: Metro Detroit has an extensive toll-free network of freeways administered by the Michigan Department of Transportation. Four major Interstate Highways surround the city. Detroit is connected via Interstate 75 (I-75) and I-96 to Kings Highway 401 and to major Southern Ontario cities such as London, Ontario and the Greater Toronto Area. I-75 (Chrysler and Fisher freeways) is the region's main north–south route, serving Flint, Pontiac, Troy, and Detroit, before continuing south (as the Detroit–Toledo and Seaway Freeways) to serve many of the communities along the shore of Lake Erie.
