At first look, the sources seem similar. They both were written around the same period and the URL appears almost identical. However, it is important to notice that source A is from a website ending in ".net," while source B ends in ".gov." Government websites are always more credible than a website ending in ".com" or ".net." Also, source A has advertisements, which means it is mostly for entertainment.
