1. number 3 is a city that asked for help from pope urban ii against attacks from the muslims.

Explanation:

1. The Angles and Saxons settled in Britain (not shown in detail in the map but generally in the area relevant to the Roman - Empire's power vacuum in the north - western part of Europe). The Goths had different branches and their settlement areas were more in the central and eastern parts of Europe. The Vikings came later and the Huns were more of a nomadic group that caused destruction rather than settling in the area relevant to the Roman - Empire's power vacuum in the traditional sense. So for question 1, the answer is c.
2. The Franks settled in the area corresponding to modern - day France (approximate location of number 2 on the map) and set up a large empire. The Visigoths were more in the Iberian Peninsula, the Vandals were in North Africa and the Iberian Peninsula, and the Ostrogoths were in Italy. So for question 2, the answer is b.
3. Constantinople (number 3 on the map) asked Pope Urban II for help against Muslim attacks, which led to the Crusades.

Answer:

1. c. Angles and Saxons
2. b. Franks
3. Constantinople (not given as an option but inferred from historical context)
