question:
Passage: In 1634, the Mughal emperor extended his hospitality to the English traders to the region of Bengal, and in 1717 completely waived customs duties for the trade. The company's mainstay businesses were by then cotton, silk, indigo dye, saltpetre, and tea. The Dutch were aggressive competitors and had meanwhile expanded their monopoly of the spice trade in the Malaccan straits by ousting the Portuguese in 1640–41. With reduced Portuguese and Spanish influence in the region, the EIC and Dutch East India Company (VOC) entered a period of intense competition, resulting in the Anglo-Dutch Wars of the 17th and 18th centuries.

What caused the Greeks to expand their spice trade in the Malaccan straits?

question:
Passage: During the Early Modern period (approximately late 15th century to 1800), the universities of Europe would see a tremendous amount of growth, productivity and innovative research. At the end of the Middle Ages, about 400 years after the first university was founded, there were twenty-nine universities spread throughout Europe. In the 15th century, twenty-eight new ones were created, with another eighteen added between 1500 and 1625. This pace continued until by the end of the 18th century there were approximately 143 universities in Europe and Eastern Europe, with the highest concentrations in the German Empire (34), Italian countries (26), France (25), and Spain (23) – this was close to a 500% increase over the number of universities toward the end of the Middle Ages. This number does not include the numerous universities that disappeared, or institutions that merged with other universities during this time. It should be noted that the identification of a university was not necessarily obvious during the Early Modern period, as the term is applied to a burgeoning number of institutions. In fact, the term "university" was not always used to designate a higher education institution. In Mediterranean countries, the term studium generale was still often used, while "Academy" was common in Northern European countries.
