Question: Post-European-contact Chamorro culture is a combination of American, Spanish, Filipino, other Micronesian Islander and Mexican traditions, with few remaining indigenous pre-Hispanic customs. These influences are manifested in the local language, music, dance, sea navigation, cuisine, fishing, games (such as batu, chonka, estuleks, and bayogu), songs and fashion. During Spanish colonial rule (16681898) the majority of the population was converted to Roman Catholicism and religious festivities such as Easter and Christmas became widespread. Post-contact Chamorro cuisine is largely based on corn, and includes tortillas, tamales, atole and chilaquiles, which are a clear influence from Spanish trade between Mesoamerica and Asia. The modern Chamorro language is a Malayo-Polynesian language with much Spanish and Filipino influence. Many Chamorros also have Spanish surnames because of their conversion to Roman Catholic Christianity and the adoption of names from the Catalogo alfabetico de apellidos, a phenomenon also common to the Philippines.
Is there an answer to this question: What language did the Chamorro speak pre-contact?

Answer: unanswerable

Question: Much of the study in the madrasah college centred on examining whether certain opinions of law were orthodox. This scholarly process of "determining orthodoxy began with a question which the Muslim layman, called in that capacity mustafti, presented to a jurisconsult, called mufti, soliciting from him a response, called fatwa, a legal opinion (the religious law of Islam covers civil as well as religious matters). The mufti (professor of legal opinions) took this question, studied it, researched it intensively in the sacred scriptures, in order to find a solution to it. This process of scholarly research was called ijtihad, literally, the exertion of one's efforts to the utmost limit."
Is there an answer to this question: What determination of the study of law was held to much debate?

Answer: whether certain opinions of law were orthodox

Question: The presence of companies like Shell in the Niger-Delta has led to extreme environmental issues in the Niger Delta. Many pipelines in the Niger-Delta owned by Shell are old and corroded. Shell has acknowledged its responsibility for keeping the pipelines new but has also denied responsibility for environmental causes. This has led to mass protests from the Niger-Delta inhabitants and Amnesty International against Shell and Friends of the Earth Netherlands. It has also led to action plans to boycott Shell by environmental groups, and human rights groups. In January 2013, a Dutch court rejected four out of five allegations brought against the firm over oil pollution in the Niger Delta but found a subsidiary guilty of one case of pollution, ordering compensation to be paid to a Nigerian farmer.
Is there an answer to this question: Many pipelines owned by Shell in the Niger Delta are described as what?

Answer:
old and corroded
