Answer:

Answer:

The missing piece of technology that prevented the audio production industry from using the electrical recording system earlier was a device that could amplify the electric signal. The device that made this possible was the Audion valve

Explanation:

The telephone system in the passage is able to convert sound to electronic signals in a crude manner, without amplification. The electrical recording system, whereby a microphone converted sound into amplified electrical signals was, made possible by the invention of the electronic valve, known as the Audion triode vacuum tube by Lee De Forest in 1906. Electrical sound systems were built based on the Audion tube before transistor-based audio equipment became commercially available in the 1950s.

It is most likely that the truck driver is preparing for a right turn.

A large panel truck driver making a wrong right hand turn can cause what is commonly known as a right hand accident. This would result into a crash from either the front or the side. It is worth noting that the bigger the vehicle, the bigger the area the truck needs to make a safe turn.
What this truck driver was trying to do is called the “jug handle” turn. His aim was to turn left first so he can get out around the corner with a wider clearance to avoid hitting anyone else on traffic. Whoever is behind would be able to stop, slow down and wait for him to negotiate the turn
