20 True or False Questions

True or False Questions

The true or false questions are those that pose only two options: that the statement is true or that it is false. Technically they are not questions (since they are not written between signs) but they are statements or statements. For example: The capital of Peru is Lima (true).

One of the problems with true and false questions is that there is a 50% success rate if chosen randomly. Therefore, they are useful for making self-evaluations and not so much for objectively evaluating others.

It is useful to ask the student to justify the cases in which the statement is false, that is, to explain why it is false or what would be the correct statement. For example: The moon revolves around the Sun. (False: the Moon revolves around Planet Earth).

A dialogue between Sherlock Holmes and John Watson, extracted from "The Sign of the Four", by Arthur Conan Doyle

“–I have heard you say that it is very difficult for a man to use an object every day without leaving the imprint of his personality on it, so that an expert observer can read it. Well, here I have a watch that has come into my possession a short time ago. Would you be kind enough to give me your opinion on the character and customs of his former owner?

I handed him the watch with a slight inner feeling of glee, as, in my opinion, the proof was impossible to overcome and with it I proposed to teach him a lesson in the somewhat dogmatic tone that he adopted from time to time. when. Holmes weighed the watch in his hand, peered at the dial, opened the back cover, and examined the gear, first with the naked eye and then with the aid of a powerful magnifying glass. I couldn't help but smile at his downcast expression on his when he finally closed the lid and handed it back to me.

"There is hardly any data," he said. This watch was recently cleaned, which deprives me of the most suggestive clues.

"He's right," I replied. They cleaned it up before they sent it to me. In my heart of hearts, I accused my partner of using a weak and powerless excuse to justify his failure. What data had he expected to find even if the watch hadn't been clean?

"But even if it's not satisfactory, my research has not been entirely sterile," he commented, looking up at the ceiling with his dreamy, expressionless eyes. Unless you correct me, I would say that the watch belonged to his older brother, who in turn inherited it from his father.

"I suppose you deduced that from the initials H.W. engraved on the back.

-Indeed. The W suggests his last name. The date on the watch is almost fifty years ago, and the initials are as old as the watch. Therefore, it was manufactured in the previous generation. These jewels are usually inherited by the eldest son, and it is quite likely that he is named after his father. If I remember correctly, his father passed away many years ago. Therefore, the watch has been in the hands of his older brother.

"So far, fine," I said. Anything else?

"He was a man with disorderly habits... very dirty and neglected." He had good prospects, but he missed opportunities, lived for some time in poverty, with occasional brief intervals of prosperity, and finally took to drink and died. That's all I can get. (…)

"How the hell did you find out all that?" Because he has been right in all the details.

- I limited myself to saying what seemed more likely (...) For example, I began by stating that his brother was careless. If you look at the bottom of the watch cover, you will see that it not only has a couple of dents, but is also scratched and scratched everywhere, due to the habit of putting other hard objects in the same pocket, such as coins or keys. You see, it is no feat to suppose that a man who treats a fifty-guinean watch so lightly must be careless. Nor is it so far-fetched to deduce that a man who inherits such a valuable item must be well provided for in other respects. It is the custom of English moneylenders, when someone pawns a watch, to engrave the number of the ballot with a pin on the inside of the cover. It is more convenient than putting a label and there is no danger that the number will be lost or misplaced. And my magnifying glass has discovered no less than four of those numbers on the inside of the watch cover. Deduction: her brother had frequent financial difficulties. Secondary deduction: he from time to time he went through periods of prosperity, otherwise he would not have been able to play the pledge. Finally, please look at the inner sheet, where the winding hole is. Notice that there are thousands of scratches around the hole, caused by slipping the key from the string. Do you think a sober man's key would leave all those marks? Yet they are never missing from a drunkard's watch. He wound it up at night and left the mark of his shaking hand. "

1. The previous owner of the watch was John Watson's older brother.
2. The watch had been pawned at least four times.
3. The markings on the lid indicated that the previous owner drank alcohol excessively.
