Source C is a cartoon drawn by Bernard Partridge in 1906. The cartoon has pictures of two women, one a Suffragist and one a Suffragette. The title of the picture is "The Shrieking Sister". The word "shrieking" implies that the woman is mad, crazy and not stable. This is the word Bernard Partridge uses to describe the woman on the right - the Suffragette. But the woman on the left - the Suffragist - is portrayed as sensible, calm and presentable. This tells us straight away that Bernard Partridge was not against Suffragist movement but did not agree with Suffragette activities which was a very unusual opinion at the time. This was because the WSPU was just formed the year before and they caused riots and broke several laws and most men at the time were opposed to the whole suffrage movement. However the title that Bernard Partridge uses makes us believe otherwise, he uses the word "sister" to describe the mad woman which implies that they were together. I believe that Bernard Partridge believed that some women should get the right to vote which was very unusual at the time.
An important factor that may affect the information of these sources is the time they were drawn and said. Source B - the speech by Lloyd George - was said in 1913 while Source C - the picture drawn by Bernard Partridge - was drawn in 1906. There is a 7 year difference between the sources and many situations had occurred during these years that may have changed opinions of either people. For example, Lloyd George could have been in support of the suffrage activities but his mind could have changed when the Suffragettes burnt down his house and Bernard Partridge could also been against some of the tactics the Suffragists took and would have changed his opinion and been against the suffrage campaign altogether. So in general, under the circumstances of the incidents that occurred during the years of 1906 and 1913, people's opinions may have differed a lot which could have affected the reliability of both sources.
