The Nobel Peace Prize was not awarded in 1942 due to World War II. This occurred during 1939-1943. Alfred Nobel founded the prizes, Einstein won Physics in 1921, and Max Planck won Physics in 1918.
A
Correct answer
Explanation
Clarence Birdseye (1886-1956) was indeed the American inventor who developed the quick-freezing process for food in the 1920s. His observation of how Inuit people preserved fish by freezing it quickly inspired his flash-freezing method, which revolutionized the food industry and led to the frozen food brand named after him.

Daniel Nestor
-
Tenzin Norzon
A
Correct answer
Explanation
Craig Venter and his team at the J. Craig Venter Institute created the first synthetic living cell in 2010 by designing and chemically synthesizing a complete bacterial genome, then transplanting it into a recipient cell. This groundbreaking achievement in synthetic biology demonstrated that artificially created life forms could be constructed from scratch.

-
electric vote recorder
-
printing telegraph
-
stock ticker
-
automatic telegraph
A
Correct answer
Explanation
Thomas Edison's first patent was US Patent 90,646 for the electric vote recorder, filed in 1869 when he was 22 years old. This device allowed legislators to vote yes or no by turning a switch, which would record votes electronically. Unfortunately, it was not commercially successful because politicians were unwilling to speed up voting processes. Edison vowed to only invent things people would actually buy after this failure.
B
Correct answer
Explanation
This is false. In 1877, Edison invented the first phonograph prototype, but he used wax paper wrapped around the grooved cylinder, not tin foil. The tin foil version came slightly later as an improvement. The wax paper version could record and play back sound, but the quality was poor. Edison continued refining the design, eventually using tin foil and later wax cylinders for better sound reproduction.
-
movie camera
-
telephone
-
electron microscope
-
x-ray
D
Correct answer
Explanation
Edison's fluoroscope was an early X-ray imaging device that used fluorescent screens to make X-ray images visible in real-time. This technology became commonly known as X-ray imaging or simply 'X-rays' in medical practice. Edison himself stopped working on X-ray technology after his assistant Clarence Dally suffered severe radiation damage and died from X-ray exposure, highlighting the dangers of early radiography.
-
Menlo Park
-
West Orange
-
South Orange
-
East Orange
B
Correct answer
Explanation
Thomas Edison developed the first motion picture film (movie) at his laboratory in West Orange, New Jersey in 1889. This was a significant breakthrough in cinema history, building on his earlier work with the phonograph. West Orange became Edison's primary research facility where he developed many of his most famous inventions, including improvements to the motion picture camera and projector. Menlo Park was his earlier laboratory site.
