Hello. You did not provide the text to which this question refers, which makes it impossible for me to be able to answer your question accurately. However, to try to help I will show you concitos that can guide you to find the correct answer. I hope this helps you.
A historical situation is a historical event that is being described in your text. This historic event represents an important event for civilization and occurred many years ago. To find it, you must read its text and interpret what period, event and historical situation it is presented.
To find an argument shown in the text, you must find an author's position on the historical event presented. An example of argument can be seen in a text that states that slavery contributed to the construction of racism in modern society.
A historical effect is the result that this historical event has developed and which can be seen today, once again, the example given in the previous paragraph on the relationship between scracvidão and racismo, can be presented here, as a historical effect.
