Silent Military Communication

How could a member of the military communicate silently and without light?

By using braille.

Braille was based on a tactile military code called night writing, developed by Charles Barbier in response to Napoleon’s demand for a means for soldiers to communicate silently at night and without light. In Barbier’s system, sets of 12 embossed dots encoded 36 different sounds. It proved to be too difficult for soldiers to recognize by touch and was rejected by the military.

I’m Usually Quite Pleasant

I’m usually quite pleasant
As you roam and play,
But if you look into my eyes,
I’ll not look away.

Once you turn away from me,
I’ll attack if I stay dry,
Better grab a pail of water,
I’ll not stop until I die.

What am I?

An Enderman, from Minecraft.

Enderman are normally passive, but they become hostile if a player looks directly at them. The Enderman will stare back until the player looks away, and then attack the player. A bucket of water is the best way to defeat an Enderman.

3 4 5 28 20

5 6 7 66 42

91. To get the number in the fourth column, you add the numbers in column 1 and 2, then multiply by the number in column 2. f(n,m) = (n + m) * m
For example, f(2,3) = (2 + 3) * 3 = 15. Thus f(6,7) = (6 + 7) * 7 = 91
