Choice B is the best answer because it most accurately describes the function of the underlined sentence in the text as a whole. The text discusses the Bayeux Tapestry, making the point that the workers who produced the huge tapestry in the eleventh century might not have ever produced a tapestry so large before. The text goes on to suggest that because of this lack of previous experience, the workers developed and refined the process of joining the tapestry’s panels over time as they worked. The last sentence of the text then provides an example of an observation that suggests the workers’ process changed: clear misalignment ofthe borders of the two panels the workers joined first and virtually invisible joins completed later. Thus, the underlined sentence serves to support an argument about the workers who produced the tapestry. 
Choice A is incorrect because the example given in the last sentence of the text has to do with how the panels of the Bayeux Tapestry were joined by the workers, not with what is depicted in those panels; the text never identifies any people or places depicted in the tapestry. Choice C is incorrect because the last sentence compares how early panels in the Bayeux Tapestry were joined with how later panels in the same tapestry were joined; it doesn’t make any comparison between the Bayeux Tapestry and other tapestries from the same time in France. Choice D is incorrect because the last sentence doesn’t address the location where the Bayeux Tapestry was created; the first sentence of the text presents it as a given that the tapestry was created in France, but nothing in the text indicates how that origin was determined.
