Hey, let’s play this game where you go from one fact to its exact opposite, via the Wikipedia, in the smallest possible number of steps:
P-51 Mustang: “Chuck Yeager, flying a P-51D, was the first Allied pilot to shoot down a Me 262 when he surprised it during its landing approach.”
… is a link away from …
Me 262: “The Tempest was the first Allied plane to shoot down a Me262 …”
Hay fever: “Short-acting antihistamines, which are generally over-the-counter (non-prescription), often relieve mild to moderate symptoms, but can cause drowsiness. … One formerly prescription medication, loratadine (Claritin), is now available over the counter.”
… is a link away from …
Loratadine: “Loratadine is a tricyclic antihistamine, which has a selective and peripheral H1-antagonist action. It has a long-lasting effect …”
You can do this with the Britannica too, although you might need to look at different editions:
Britannica (1985): “While the Cultural Revolution can hardly be seen as the logically inevitable outcome of Mao’s previous ideas and career, he so thoroughly identified himself with this attempt to transform the whole spirit and structure of Chinese society that assessment of the man and his life work must begin with it.”
Britannica (2002): “While the Cultural Revolution was an entirely logical culmination of Mao’s last two decades, it was by no means the only possible outcome of his approach to revolution, nor need a judgment of his work as a whole be based primarily on this last phase.”
