QUES: In 1852, Elisha Otis introduced the safety elevator, which prevented the fall of the cab if the cable broke. The design of the Otis safety elevator is somewhat similar to one type still used today. A governor device engages knurled roller(s), locking the elevator to its guides should the elevator descend at excessive speed. He demonstrated it at the New York exposition in the Crystal Palace in a dramatic, death-defying presentation in 1854, and the first such passenger elevator was installed at 488 Broadway in New York City on March 23, 1857.
What feature did the safety elevator display?

ANS: prevented the fall of the cab if the cable broke

QUES: The trends of Hellenization were therefore accompanied by Greeks adopting native ways over time, but this was widely varied by place and by social class. The farther away from the Mediterranean and the lower in social status, the more likely that a colonist was to adopt local ways, while the Greco-Macedonian elites and Royal families, usually remained thoroughly Greek and viewed most non-Greeks with disdain. It is only until Cleopatra VII, that a Ptolemaic ruler bothered to learn the Egyptian language of their subjects.
Who was the first Ptolemaic ruler to learn the Egyptian language?

ANS: Cleopatra VII

QUES: Certain types of musical instruments, such as those of the violin family, the guitar, the clarinet and recorder, the xylophone, and the marimba, are traditionally made mostly or entirely of wood. The choice of wood may make a significant difference to the tone and resonant qualities of the instrument, and tonewoods have widely differing properties, ranging from the hard and dense african blackwood (used for the bodies of clarinets) to the light but resonant European spruce (Picea abies), which is traditionally used for the soundboards of violins. The most valuable tonewoods, such as the ripple sycamore (Acer pseudoplatanus), used for the backs of violins, combine acoustic properties with decorative color and grain which enhance the appearance of the finished instrument.
What expensive wood with a prized color is used to make the backs of violins?

ANS: ripple sycamore

QUES: In the 17th century, the Somers Isles Company suppressed shipbuilding, as it needed Bermudians to farm to generate income from the land. Agricultural production met with limited success, however. The Bermuda cedar boxes used to ship tobacco to England were reportedly worth more than their contents.[citation needed] The colony of Virginia far surpassed Bermuda in both quality and quantity of tobacco produced. Bermudians began to turn to maritime trades relatively early in the 17th century, but the Somers Isles Company used all its authority to suppress turning away from agriculture. This interference led to the islanders demanding, and receiving, the revocation of the Company's charter in 1684, and the Company was dissolved.
Why was the Somers Isles Company's charter revoked?

ANS:
islanders demanding
