“All birds lay eggs”. The birds circle must be inside the egg circle. From only the information above, we don’t know if the birds are mammals or not. So, the answer must look like the Venn diagram we drew above, with another circle inside the egg circle. Look at all the answers and see which one resembles what we are looking for. Therefore, the answer must be C. B looks similar too, but this is not the answer as the bird circle must be completely within the egg circle not just overlapping it.
I hope this article has made Venn diagram questions easier to solve. The most important thing to remember are to mind the wording when drawing or interpreting Venn diagram questions. Also, ensure you do not panic when you see a question you don’t understand. Flag, then come back if you have time and try to solve it with a clear mind.
