What can we learn from the passage?

参考解析：

推理判断题。根据第三段第四句“honey’s texture and consistency are good for keeping wounds clean”可知，蜂蜜可治疗伤口，A项正确；根据第二段最后一句“It may have more minerals...“可知，蜂蜜有很多的矿物质，但未和sugar比较，B项错误；根据第三段最后一句“The sticky substance means bacteria cannot accumulate and multiply easily. It is particularly well-known for fighting bacteria like staph”可知，是蜂蜜中的粘性物质，并非蜂蜜中的糖分，可以抵抗细菌，C项错误；根据第四段的“scientists can only say this for sure about Makuna and Malaysian Tualang honey”可知，并非所有蜂蜜都可以用于医疗方面，D项错误。故选A。
