In 1961, Time magazine selected as its Man of the Year not a specific person but “the American Scientist.” The choice was an indication of the widespread fascination with which Americans in the age of atomic power viewed science and technology. Identify which of the following statements correctly describe scientific and technological breakthroughs and/or describe their effects on American life. 1. DDT was an effective pesticide that was later found to be harmful to animals and humans. 2. The antibiotic penicillin and a vaccine for diabetes were developed in the 1940s and 1950s. 3. The transistor, developed in 1948, allowed for the miniaturization of devices such as radios, televisions, and hearing aids. 4. IBM developed the first UNIVAC computer, which predicted Eisenhower's 1952 election victory. 5. The Apollo program was created for the purpose of landing astronauts on the moon. 6. The plutonium bomb, with its fission process, gave significant impetus to the effort to develop unmanned rockets.

Correct: DDT was indeed an effective pesticide that was later found to be harmful to animals and humans. It was widely used in the mid-20th century before its harmful effects were fully understood.

Partially correct: The antibiotic penicillin was indeed developed in the 1940s. However, a vaccine for diabetes has not been developed. Insulin, which is a treatment for diabetes, was discovered in the 1920s.

Correct: The transistor, developed in 1948, did indeed allow for the miniaturization of devices such as radios, televisions, and hearing aids. It was a significant technological breakthrough.

Incorrect: IBM did not develop the first UNIVAC computer. The UNIVAC computer was developed by J. Presper Eckert and John Mauchly through their company, which was later bought by Remington Rand. The UNIVAC did predict Eisenhower's 1952 election victory, though.

Correct: The Apollo program was indeed created for the purpose of landing astronauts on the moon. This was a major focus of the American space program in the 1960s.

Partially correct: The development of the plutonium bomb did indeed give impetus to the effort to develop unmanned rockets. However, the plutonium bomb involves a fission process, not a fusion process.
