QUES: One major difference between Baroque music and the classical era that followed it is that the types of instruments used in ensembles were much less standardized. Whereas a classical era string quartet consists almost exclusively of two violins, a viola and a cello, a Baroque group accompanying a soloist or opera could include one of several different types of keyboard instruments (e.g., pipe organ, harpsichord, or clavichord), additional stringed chordal instruments (e.g., a lute) and an unspecified number of bass instruments performing the basso continuo bassline, including bowed strings, woodwinds and brass instruments (e.g., a cello, contrabass, viol, bassoon, serpent, etc.).

Two violins, a viola, and a cello make up what type of group?
What is the answer?
ANS: a classical era string quartet
QUES: Compaq, who had previously held the third place spot among PC manufacturers during the 1980s and early-mid 1990s, initiated a successful price war in 1994 that vaulted them to the biggest by the year end, overtaking a struggling IBM and relegating Apple to third place. Apple's market share further struggled due to the release of the Windows 95 operating system, which unified Microsoft's formerly separate MS-DOS and Windows products. Windows 95 significantly enhanced the multimedia capability and performance of IBM PC compatible computers, and brought the capabilities of Windows to parity with the Mac OS GUI.

What unified Apple's MS-DOS and Windows products?
What is the answer?
ANS: unanswerable
QUES: Infrared tracking, also known as infrared homing, refers to a passive missile guidance system, which uses the emission from a target of electromagnetic radiation in the infrared part of the spectrum to track it. Missiles that use infrared seeking are often referred to as "heat-seekers", since infrared (IR) is just below the visible spectrum of light in frequency and is radiated strongly by hot bodies. Many objects such as people, vehicle engines, and aircraft generate and retain heat, and as such, are especially visible in the infrared wavelengths of light compared to objects in the background.

What is the term that uses the infrared spectrum that is radiated by hot bodies?
What is the answer?
ANS:
unanswerable
