bro lets have demonstration of applying maps by this question
Nature and Motives of Mehmood's Ghaznavi's invasions; Religious, political or economic ?

above mentioned question is of simple nature now while replying to the question you will write intro not heading but your view in short afterward before before ghaznavids motive main heading you can write " ghaznavid invaded came and went away as his reign in india clearly depicts shown in map below because his major motive of coming there was economic .
afterward you can draw his map and then prove your point by map as his territories were not sufficient for political purpose and then discussing religiously motive you can here also draw map and then prove your point as he never wanted to settle there religious purpose because if he wanted to disseminate islam there he would have conquered other areas for his excellence and for religious purpose etc etc etc
