Explanation:
Ideally, to solve these types of exercises, first read the text a few times until you understand it.
Second, you must always have a dictionary or a translator at hand to be able to search for those words that you do not understand, and thus be able to better understand the context.
Once you have understood the text, you should see which of the options is the most appropriate for the answer. You will notice that there are options that would make the sentence illogical, others that would not match in gender, others that would not match in number, etc.
Therefore, you should always check that the answers you have chosen give a logical sense to the sentence.
