Explanation: (C) This question requires information related to the stimulus material, but not directly referred to by it. In this case, the issue has to do with background and causation. Answer B is more appropriate to the Indian Ocean trade network, and the influence of D was felt earlier than the time period depicted in the map. Answer A refers to a later innovation (which allowed for the relatively easy calculation of longitude). The sailing gunship referred to in C allowed the European projection of force, and also permitted the French, English, and Dutch to compete with rivals like the Spanish and Portuguese for control over colonies and sea routes.
