Question: Extract the answer to the question from the following context. Question: What did Southeast Asian rulers do to assist with Islamification? Context: There are several theories to the Islamisation process in Southeast Asia. Another theory is trade. The expansion of trade among West Asia, India and Southeast Asia helped the spread of the religion as Muslim traders from Southern Yemen (Hadramout) brought Islam to the region with their large volume of trade. Many settled in Indonesia, Singapore, and Malaysia. This is evident in the Arab-Indonesian, Arab-Singaporean, and Arab-Malay populations who were at one time very prominent in each of their countries. The second theory is the role of missionaries or Sufis.[citation needed] The Sufi missionaries played a significant role in spreading the faith by introducing Islamic ideas to the region. Finally, the ruling classes embraced Islam and that further aided the permeation of the religion throughout the region. The ruler of the region's most important port, Malacca Sultanate, embraced Islam in the 15th century, heralding a period of accelerated conversion of Islam throughout the region as Islam provided a positive force among the ruling and trading classes.
Answer: embraced Islam

Question: Extract the answer to the question from the following context. Question: Some eggs stay? Context: However, the lifecycles of most living polychaetes, which are almost all marine animals, are unknown, and only about 25% of the 300+ species whose lifecycles are known follow this pattern. About 14% use a similar external fertilization but produce yolk-rich eggs, which reduce the time the larva needs to spend among the plankton, or eggs from which miniature adults emerge rather than larvae. The rest care for the fertilized eggs until they hatch – some by producing jelly-covered masses of eggs which they tend, some by attaching the eggs to their bodies and a few species by keeping the eggs within their bodies until they hatch. These species use a variety of methods for sperm transfer; for example, in some the females collect sperm released into the water, while in others the males have a penis that inject sperm into the female. There is no guarantee that this is a representative sample of polychaetes' reproductive patterns, and it simply reflects scientists' current knowledge.
Answer: within their bodies until they hatch

Question: Extract the answer to the question from the following context. Question: How was it viewed? Context: Vinyl records can be warped by heat, improper storage, exposure to sunlight, or manufacturing defects such as excessively tight plastic shrinkwrap on the album cover. A small degree of warp was common, and allowing for it was part of the art of turntable and tonearm design. "wow" (once-per-revolution pitch variation) could result from warp, or from a spindle hole that was not precisely centered. Standard practice for LPs was to place the LP in a paper or plastic inner cover. This, if placed within the outer cardboard cover so that the opening was entirely within the outer cover, was said to reduce ingress of dust onto the record surface. Singles, with rare exceptions, had simple paper covers with no inner cover.
Answer:
it was part of the art of turntable and tonearm design
