Problem: For example, 19201080p25 identifies progressive scanning format with 25 frames per second, each frame being 1,920 pixels wide and 1,080 pixels high. The 1080i25 or 1080i50 notation identifies interlaced scanning format with 25 frames (50 fields) per second, each frame being 1,920 pixels wide and 1,080 pixels high. The 1080i30 or 1080i60 notation identifies interlaced scanning format with 30 frames (60 fields) per second, each frame being 1,920 pixels wide and 1,080 pixels high. The 720p60 notation identifies progressive scanning format with 60 frames per second, each frame being 720 pixels high; 1,280 pixels horizontally are implied.
What size is each 1920x1080p25 frame?
The answer is the following: 1,920 pixels wide and 1,080 pixels high

Problem: Interstate 10, which runs southeast to northwest through town, connects Tucson to Phoenix to the northwest on the way to its western terminus in Santa Monica, California, and to Las Cruces, New Mexico and El Paso, Texas toward its eastern terminus in Jacksonville, Florida. I-19 runs south from Tucson toward Nogales and the U.S.-Mexico border. I-19 is the only Interstate highway that uses "kilometer posts" instead of "mileposts", although the speed limits are marked in miles per hour instead of kilometers per hour.
What is unusual about I-19?
The answer is the following: the only Interstate highway that uses "kilometer posts" instead of "mileposts"

Problem: Although STOVL aircraft are capable of taking off vertically from a spot on the deck, using the ramp and a running start is far more fuel efficient and permits a heavier launch weight. As catapults are unnecessary, carriers with this arrangement reduce weight, complexity, and space needed for complex steam or electromagnetic launching equipment, vertical landing aircraft also remove the need for arresting cables and related hardware. Russian, Chinese, and future Indian carriers include a ski-jump ramp for launching lightly loaded conventional fighter aircraft but recover using traditional carrier arresting cables and a tailhook on their aircraft.
What do Russian carriers still use to recover?
The answer is the following: traditional carrier arresting cables and a tailhook on their aircraft

Problem: Gustav had a preference for his elder son, Meinhard (July 17, 1946 May 20, 1971), over Arnold. His favoritism was "strong and blatant," which stemmed from unfounded suspicion that Arnold was not his biological child. Schwarzenegger has said his father had "no patience for listening or understanding your problems." Schwarzenegger had a good relationship with his mother and kept in touch with her until her death. In later life, Schwarzenegger commissioned the Simon Wiesenthal Center to research his father's wartime record, which came up with no evidence of Gustav's being involved in atrocities, despite Gustav's membership in the Nazi Party and SA. Schwarzenegger's father's background received wide press attention during the 2003 California recall campaign. At school, Schwarzenegger was apparently in the middle but stood out for his "cheerful, good-humored and exuberant" character. Money was a problem in their household; Schwarzenegger recalled that one of the highlights of his youth was when the family bought a refrigerator.
What appliance did Schwarzenegger's family buy that he called a highlight of his youth?
The answer is the following:
refrigerator
