Thanks to scientific advances and goals, some Pharmaceutical crops, which are transgenic crops used to produce medical drugs, are approved for clinical use. Although there are risks, the benefits outweigh them and hopefully, the tedious researches will lead to a great pay-off.
Answer:
Why would the introduction of Christianity to the Igbo people create conflict? ... Some villagers became Christian and others did not, so the villagers were no longer unified by long-established customs.
I would definitely go with letter choice C. A doesn't make sense because the transitive verb depends on a direct object in order to exist, not the subject of the sentence. B can't be it, because the transitive verb is an action verb linked to the Direct Object, without the DO it is just an action verb. D doesn't even mention the purpose of the transitive verb. So C would definitely be correct. Hope that Helps.
