Passage One
From the goose that laid the golden egg to the race between the tortoise and the hare, Aesop’s fables are known for teaching moral lessons rather than literally being true. But a new study says at least one such tale might really have happened.
It’s the fable about a thirsty crow. The bird comes across a jar with the water level too low for him to reach. The crow raises the water level by dropping stones into the jar. The moral tells: Little by little does the trick, or in other retellings, necessity is the mother of invention.
Now, scientists report that some relatives of crows called rooks used the same stone-dropping strategy to get at a floating worm. Results of experiments with three birds were published online by the journal Current Biology.
Rooks, like crows, had already been shown to use tools in previous experiments. Christopher Bird of Cambridge University and a colleague exposed the rooks to a 6-i

| The golden rule for good writing is not
a rule of grammar. It is true that there are rules of grammar, as in music there
are rules of harmony, and that they are important, but one can no more write
good English merely by keeping these rules than one can compose good music. The
