Q:I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "Egypt has one of the oldest civilisations in the world. It has been in contact with many other civilisations and nations and has been through so many eras, starting from prehistoric age to the modern age, passing through so many ages such as; Pharonic, Roman, Greek, Islamic and many other ages. Because of this wide variation of ages, the continuous contact with other nations and the big number of conflicts Egypt had been through, at least 60 museums may be found in Egypt, mainly covering a wide area of these ages and conflicts."?
A:
what is the fourth age mentioned?
