Baroque instruments included some instruments from the earlier periods (e.g., the hurdy-gurdy and recorder) and a number of new instruments (e.g, the cello, contrabass and fortepiano). Some instruments from previous eras fell into disuse, such as the shawm and the wooden cornet. The key Baroque instruments for strings included the violin, viol, viola, viola d'amore, cello, contrabass, lute, theorbo (which often played the basso continuo parts), mandolin, cittern, Baroque guitar, harp and hurdy-gurdy. Woodwinds included the Baroque flute, Baroque oboe, rackett, recorder and the bassoon. Brass instruments included the cornett, natural horn, Baroque trumpet, serpent and the trombone. Keyboard instruments included the clavichord, tangent piano, the fortepiano (an early version of the piano), the harpsichord and the pipe organ. Percussion instruments included the timpani, snare drum, tambourine and the castanets.
Which string instrument often played the basso continuo parts?
theorbo

Input: Light-emitting diode
Many sensor systems rely on light as the signal source. LEDs are often ideal as a light source due to the requirements of the sensors. LEDs are used as motion sensors, for example in optical computer mice. The Nintendo Wii's sensor bar uses infrared LEDs. Pulse oximeters use them for measuring oxygen saturation. Some flatbed scanners use arrays of RGB LEDs rather than the typical cold-cathode fluorescent lamp as the light source. Having independent control of three illuminated colors allows the scanner to calibrate itself for more accurate color balance, and there is no need for warm-up. Further, its sensors only need be monochromatic, since at any one time the page being scanned is only lit by one color of light. Since LEDs can also be used as photodiodes, they can be used for both photo emission and detection. This could be used, for example, in a touchscreen that registers reflected light from a finger or stylus. Many materials and biological systems are sensitive to, or dependent on, light. Grow lights use LEDs to increase photosynthesis in plants, and bacteria and viruses can be removed from water and other substances using UV LEDs for sterilization.

What video game console uses infrared LEDs?
Output: Nintendo Wii

Input: Article: Traditionally, Espanyol was seen by the vast majority of Barcelona's citizens as a club which cultivated a kind of compliance to the central authority, in stark contrast to Barca's revolutionary spirit. Also in the 1960s and 1970s, while FC Barcelona acted as an integrating force for Catalonia's new arrivals from poorer regions of Spain expecting to find a better life, Espanyol drew their support mainly from sectors close to the regime such as policemen, military officers, civil servants and career fascists.

Now answer this question: From where did Espanyol draw their supporters?

Output: close to the regime

Article: On 29 October 1956, Israeli forces crossed the Sinai Peninsula, overwhelmed Egyptian army posts, and quickly advanced to their objectives. Two days later, British and French planes bombarded Egyptian airfields in the canal zone. Nasser ordered the military's high command to withdraw the Egyptian Army from Sinai to bolster the canal's defenses. Moreover, he feared that if the armored corps was dispatched to confront the Israeli invading force and the British and French subsequently landed in the canal city of Port Said, Egyptian armor in the Sinai would be cut off from the canal and destroyed by the combined tripartite forces. Amer strongly disagreed, insisting that Egyptian tanks meet the Israelis in battle. The two had a heated exchange on 3 November, and Amer conceded. Nasser also ordered blockage of the canal by sinking or otherwise disabling forty-nine ships at its entrance.

Question: Who wanted the Egyptian armored units to fight the Israelis?
Ans: Amer

Here is a question about this article: However, from 1971 to 1975, NBA teams played preseason exhibitions against American Basketball Association teams. In the early days of the NBA, league clubs sometimes challenged the legendary barnstorming Harlem Globetrotters, with mixed success. The NBA has played preseason games in Europe and Asia. In the 2006 and 2007 seasons, the NBA and the primary European club competition, the Euroleague, conducted a preseason tournament featuring two NBA teams and the finalists from that year's Euroleague.[citation needed] In the 1998-99 and 2011-12 seasons, teams were limited to only two preseason games due to lockouts.
What is the answer to this question: When did the NBA play preseason games against the ABA?
****
So... 1971 to 1975

Article: During the later Roman Empire, the principal military developments were attempts to create an effective cavalry force as well as the continued development of highly specialised types of troops. The creation of heavily armoured cataphract-type soldiers as cavalry was an important feature of the 5th-century Roman military. The various invading tribes had differing emphasis on types of soldiersranging from the primarily infantry Anglo-Saxon invaders of Britain to the Vandals and Visigoths, who had a high proportion of cavalry in their armies. During the early invasion period, the stirrup had not been introduced into warfare, which limited the usefulness of cavalry as shock troops because it was not possible to put the full force of the horse and rider behind blows struck by the rider. The greatest change in military affairs during the invasion period was the adoption of the Hunnic composite bow in place of the earlier, and weaker, Scythian composite bow. Another development was the increasing use of longswords and the progressive replacement of scale armour by mail armour and lamellar armour.

Question: Along with lamellar armor, what armor replaced scale armor?
Ans:
mail
