With no explanation, label text_A→text_B with either "DON'T KNOW", "NO" or "YES".
text_A: Queen Louise wanted her eldest son to marry as well as had her two daughters, Alexandra and Dagmar. The UK's Queen Victoria had two unwed daughters, Princess Louise and Princess Helena, and Louise had wanted Frederick to marry either her or her sister. However, Victoria did not want her daughters to marry heirs to foreign thrones, as this would force them to live abroad, instead preferring German princes who could establish homes in England. In addition, Victoria had always been pro-German and another Danish alliance (Frederick's sister, Alexandra, had married Victoria's eldest son Edward, Prince of Wales), would not have been in line with her German interests.
text_B: Regardless of whether or not this might have impacted her decision, is there any chance that the young woman who was presumed to be eligible for marriage to Frederick had a different last name than Victoria herself?
NO.
