To design true and false questions it is important to take into account certain guidelines:
- Ask questions that are definitely false or definitely true, not those that could be true or false depending on the case.
- Sentences should be short.
- Sentences should be concise, meaning that they should avoid any accessory content.
- False sentences should not be differentiated from true sentences by length or style.
- A single idea, concept or piece of information should be evaluated in each question.
- Absolute terms (always, never, all) will only be used where necessary.
- Sentences should not be copied verbatim from textbooks.
- Prayers should always be positive.
One of the problems with true and false questions is that there is a 50% success rate just by choosing at randomTherefore, it is not very useful for making objective evaluations of third parties, but it is useful for performing self-evaluations. In other words, during the learning process, students can use true or false questions to check their knowledge and especially mark those that they cannot answer, to strengthen the study.
When these types of questions are used in the study process, it is useful that an explanation or correction of the false answers is included in the list of correct answers.
The true or false questions are often used in text comprehension, both texts in Spanish and foreign languages.
Examples of true or false questions

- There are autotrophic animals.
- Lichens are the symbiotic union of a fungus and an alga.
- Spiders are insects.

Reading Comprehension
A dialogue between Sherlock Holmes and John Watson, taken from "The Sign of 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 came into my possession a short time ago. Would you be so kind as to give me your opinion on the character and customs of its former owner?
I handed him the watch with a slight inner feeling of glee, since, in my opinion, the test was impossible to pass and with it I proposed to teach him a lesson in the somewhat dogmatic tone that he adopted from time to time. Holmes weighed the watch in his hand, looked closely 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 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 before sending it to me. In my heart, I accused my partner of using a weak and impotent excuse to justify his failure. What data had he expected to find even though 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 your 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 has the same name as the 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 careless." He had good prospects, but he missed opportunities, lived for a 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 all over the place, 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 supplied 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 on it 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: His brother was in financial difficulties frequently. Secondary deduction: from time to time he went through periods of prosperity, otherwise he would not have been able to perform 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 the key slipping off the string.Do you think a sober man's key would leave all those marks? Yet they are never lacking on a drunkard's watch. He wound it up at night and left the mark of his trembling hand. "
- The previous owner of the watch was John Watson's older brother.
- The watch had been pawned at least four times.
- The markings on the lid indicated that the previous owner drank alcohol excessively.
