Bottlemaster plastic stoppers, which cannot leak, crumble, or mold, have long been available to winemakers, at a price slightly higher than that of traditional cork stoppers. Cork prices, however, are expected to rise dramatically in the near future. Clearly, therefore, winemakers who still use cork but wish to keep production costs from rising will be forced to reconsider plastic stoppers. And since the winebuying public’s association of plastic stoppers with poorquality wine is weakening, there is an excellent chance that the Bottlemaster plastic stopper will gain an increased share of the marked for winebottle stoppers.In the argument given, the two portions in boldface play which of the following roles?A.

Du Bois advised African Americans to stop agitating for equality and to proclaim their solidarity with White Americans for the duration of the First World War.
