Take the following as truth: The conquest of space has moved ahead with breath-taking speed since the Space Age began on October 4, 1957, says the 1960 edition of the World Book , without shame because it's just an inanimate object and can't feel shame, unlike some kind of Space World Book of the future that will know all human emotions and will be perfected any minute.
Then the following statement: "In 1960, the World Book said that space conquest had accelerated tremendously in the previous three years." is true, false, or inconclusive?
Answer: True
