What do you mean? They're one and the same. Or is there a typo?

I heard that tannin is good for combating snake venom...

That brings me back some bad memories. My cataract surgery was indeed successful, though now I am scared visualizing the many things they did to my eye.

Well, the sentences "Islamic authorities pronounced the drink intoxicating and therefore prohibited by the Qurʾān" sounds like "the drink" (refers to coffee) is prohibited explicitly in the Qurʾān.

Whatever the actual origin of coffee, its stimulating effect undoubtedly made it popular. Ironically, though Islamic authorities pronounced the drink intoxicating and therefore prohibited by the Qurʾān, many Muslims were attracted to the beverage as a substitute for alcohol, also prohibited by the Qurʾān.

Huh? I am a Muslim and nowhere in the Qurʾān stated that coffee is prohibited, though they did prohibit alcohol.

Why did I never realize this, even though I saw them when eating some fried frogs.

A die is tossed 100 times. What's the expected frequency that the number appears will be 4?

The probability is 1/6, so the expected frequency is 1/6 × 100, but that results in a fraction (16 2/3). Do we need to round it up or down? Is the answer 16 or 17?
