Answer: The different techniques to find relevant information can be to search for media that are known and have a high-reliability rate, rely on other media, and read.
Explanation: Today information is available to anyone, but that does not mean that all information is true. To search for relevant information it is important to start by using means that are recognized and have validity, since if they are valid it gives a go-ahead that most of the information has the necessary rigor to be there.
It is also important to rely on other sources to be able to counter or verify the first-hand information that you have. In any process, reading is essential, but it has to be a deep reading since many times, when looking for information, it is not read correctly and this does not help to distinguish the information that is had.
