What present-day device did the invention of the transistor most directly influence?

a) automobile
b) light bulb
c) atomic bomb
d) laptop computer

The correct option is D

The transistor is a semiconductor electronic device used to deliver an output signal in response to an input signal. It fulfills functions of amplifier, oscillator, switch or rectifier. Currently it is found in virtually all electronic devices for daily use such as radios, televisions, audio and video players, quartz watches, computers, fluorescent lamps, tomographs, cell phones, although almost always within the so-called integrated circuits.

The other objects named do not have transistors.

answer: secession

secession, as it applies to the outbreak of the american civil war, comprises the series of events that began on december 20, 1860, and extended through june 8 of the next year when eleven states in the lower and upper south severed their ties with the union. the first seven seceding states of the lower south set up a provisional government at montgomery, alabama. after hostilities began at fort sumter in charleston harbor on april 12, 1861, the border states of virginia, arkansas, tennessee, and north carolina joined the new government, which then moved its capital to richmond, virginia. the union was thus divided approximately on geographic lines. twenty-one northern and border states retained the style and title of the united states, while the eleven slave states adopted the nomenclature of the confederate states of america.
