QUES: Contrary to popular belief, if placed properly and prepared-for, drums could be effectively used and heard on even the earliest jazz and military band recordings. The loudest instruments such as the drums and trumpets were positioned the farthest away from the collecting horn. Lillian Hardin Armstrong, a member of King Oliver's Creole Jazz Band, which recorded at Gennett Records in 1923, remembered that at first Oliver and his young second trumpet, Louis Armstrong, stood next to each other and Oliver's horn could not be heard. "They put Louis about fifteen feet over in the corner, looking all sad." For fading instrumental parts in and out while recording, some performers were placed on a moveable platform, which could draw the performer(s) nearer or further away as required.[citation needed]
What was the item called that recorded the sounds?

ANS: collecting horn

QUES: Bell worked extensively in medical research and invented techniques for teaching speech to the deaf. During his Volta Laboratory period, Bell and his associates considered impressing a magnetic field on a record as a means of reproducing sound. Although the trio briefly experimented with the concept, they could not develop a workable prototype. They abandoned the idea, never realizing they had glimpsed a basic principle which would one day find its application in the tape recorder, the hard disc and floppy disc drive and other magnetic media.
What famous lab did Bell spend time working for?

ANS: Volta

QUES: Utrecht hosts several large institutions of higher education. The most prominent of these is Utrecht University (est. 1636), the largest university of the Netherlands with 30,449 students (as of 2012). The university is partially based in the inner city as well as in the Uithof campus area, to the east of the city. According to Shanghai Jiaotong University's university ranking in 2014 it is the 57th best university in the world. Utrecht also houses the much smaller University of Humanistic Studies, which houses about 400 students.
What was Shanghai Jiaotong University ranked in 2014?

ANS: unanswerable

QUES: The effects of local surface low pressure are extremely limited because upper-level subsidence still continues to block any form of air ascent. Also, to be protected against rain-bearing weather systems by the atmospheric circulation itself, the desert is made even drier by his geographical configuration and location. Indeed, the extreme aridity of the Sahara can't be only explained by the subtropical high pressure. The Atlas Mountains, found in Algeria, Morocco and Tunisia also help to enhance the aridity of the northern part of the desert. These major mountain ranges act as a barrier causing a strong rain shadow effect on the leeward side by dropping much of the humidity brought by atmospheric disturbances along the polar front which affects the surrounding Mediterranean climates.
What is blocked due to local surface low pressure?

ANS:
air ascent
