1)Source A come from Guardian archive so the Source could be neutral.Source shows me a photograph of soldiers who were brutally beat up by the rioters,
and the rioters also throw stone on them and had caused injury to the soldiers.As shown in Source A British soldiers is the victim of the Bloody Sunday
Source D support Source A as the source tell me that problem is solve through fighting and britain is treated badly."As shown in Source D Britain has done a lot for Ireland. I think they should give(the country) to us,but i don't think it should be violence that will bring it about".
The purpose of this source is to influnce people that British is the who got hurt in the Bloody Sunday although the conflict is just between the catholic and protestant.
(2)The source is different from each other as source B shows that Protestant do not want to be united with Ireland as they felt that they are more happy if they are part of United Kingdom as they felt that they are known best in United kingdom as they have same background as shown in Source B "We positively want to be part of United kingdom not in the negative sense that we fear a united Ireland ....do have a feeling of belonging....we feel united in term of our common history"
However Source C state a different thing as Souce c tells me that they want
to stop all the conflict and want to be united and they also want to build friendship among each other although they are only different in religion,as shown in source C"hopefully our kids will keep theirfriendship with each other when they go back and will pass along the idea that to hate someone"
The purpose of the Source B is to make people belief that the protestant prefer to leave in United Kingdom rather than Ireland.
However the purpose for Source C is to make people that the Protestant and Catholic could leave happily together although they are from different religion.
