I have been asked to make some questions somewhat easier and I will try to accommodate that wish. It doesn't mean that the difficult questions will disappear, just that all of them will not be like that. The obvious problem then is to know what's very difficult and not, since, to some extent, that differs from person to person. However, I will try, even if I will not make anything too simple - after all, these quizzes should be a challenge. If you feel I'm not doing it well, feel free to let me know in the comment section.

Here are some new problems with which to exercise the brain. But first a look at answers and solutions to Quizzes & Puzzles 51. New problems below the image (cartoon).

Answer to Quiz 51:1

Which of the following substances are not B-vitamins?

  • Pantothenic acid

  • Pyridoxine

  • Cholecalciferol

  • Orotic acid

  • Melatonin

  • Riboflavin

  • Pangamic acid

  • Salicylic acid

  • Thiamin

  • Methionine

Ascorbic acid, Cholecalciferol, Melatonin, Salicylic acid and Methionine are not B-vitamins.

Answer to Quiz 51:2

Cleopatra is a famous Egyptian ruler from history. However, she (the one we normally call just Cleopatra) was not the only one in her family (the Ptolemaic family) with that name, and she was definitely not the first. So, if we would be strict, we would also add a number to her name - which number?


She was Cleopatra VII Philopator, so the number was VII (7). You can read more about Cleopatra, her life, her conspiracies, and her possibly dramatic death in my article Cleopatra - The Serpent of the Nile?

I learned a lot from this answers. I had to go and read more about Linus Pauling. That man was really awesome.

As regards the questions, I don't really have an answer to them.

"Curls" is the right answer, that's the visible result.

"Commonwealth nations" - no, that's wrong,only two of them are so.

a+b=b+a; that's the commutative law of addition, yes it's right.

Purple is wrong.

About 52.6.... well what you say is right, but the question was about radiation therapy, not chemotherapy. Yet the same apply. Do you know why antioxidants counteract the therapy?

The aim of radiation therapy is to kill cancer cells but antioxidants protects those cancer cells thus rendering the therapy ineffective

Yes. The ooint is that radiation causes strong oxidation, by which which the cancer cells are supposed to be killed. The antioxidants block this whole mechanism.
