QUES: The rainfall inhibition and the dissipation of cloud cover are most accentuated over the eastern section of the Sahara rather than the western. The prevailing air mass lying above the Sahara is the continental tropical (cT) air mass which is hot and dry. Hot, dry air masses primarily form over the North-African desert from the heating of the vast continental land area, and it affects the whole desert during most of the year. Because of this extreme heating process, a thermal low is usually noticed near the surface, and is the strongest and the most developed during the summertime. The Sahara High represents the eastern continental extension of the Azores High, centered over the North Atlantic Ocean. The subsidence of the Sahara High nearly reaches the ground during the coolest part of the year while it limits to the upper troposphere during the hottest periods.

QUES: Once known as "the Gibraltar of the West" and "Fortress Bermuda", Bermuda today is defended by forces of the British government. For the first two centuries of settlement, the most potent armed force operating from Bermuda was its merchant shipping fleet, which turned to privateering at every opportunity. The Bermuda government maintained a local militia. After the American Revolutionary War, Bermuda was established as the Western Atlantic headquarters of the Royal Navy. Once the Royal Navy established a base and dockyard defended by regular soldiers, however, the militias were disbanded following the War of 1812. At the end of the 19th century, the colony raised volunteer units to form a reserve for the military garrison.

Question: Roman calendars show roughly forty annual religious festivals. Some lasted several days, others a single day or less: sacred days (dies fasti) outnumbered "non-sacred" days (dies nefasti). A comparison of surviving Roman religious calendars suggests that official festivals were organized according to broad seasonal groups that allowed for different local traditions. Some of the most ancient and popular festivals incorporated ludi ("games," such as chariot races and theatrical performances), with examples including those held at Palestrina in honour of Fortuna Primigenia during Compitalia, and the Ludi Romani in honour of Liber. Other festivals may have required only the presence and rites of their priests and acolytes, or particular groups, such as women at the Bona Dea rites.
Try to answer this question if possible: What traditions did the seasonal festivals incorporate?
Answer: local


Context and question: Digital-RGB LEDs are RGB LEDs that contain their own "smart" control electronics. In addition to power and ground, these provide connections for data-in, data-out, and sometimes a clock or strobe signal. These are connected in a daisy chain, with the data in of the first LED sourced by a microprocessor, which can control the brightness and color of each LED independently of the others. They are used where a combination of maximum control and minimum visible electronics are needed such as strings for Christmas and LED matrices. Some even have refresh rates in the kHz range, allowing for basic video applications.
 What is one example of where non-Digital RGB LED lights are used?
Answer:
unanswerable
