Final answer:
Fundamentalist movements in religions do not arise due to flexible interpretation of scriptures, as they emphasize strict adherence to traditional practices and beliefs, rejecting modernist interpretations and secular influences.
Step-by-step explanation:
Fundamentalist movements within any religion, like Islam or Christianity, are typically characterized by a strict adherence to what adherents perceive as the original principles & teachings of the faith. This often involves a literal interpretation of religious texts and a rejection of modernist interpretations and secular influences. Hence, fundamentalist movements usually do not develop because of flexible interpretation of scriptures, which is counter to strict adherence, nor do they align with progressive ideologies. The key aspect of such movements is to maintain traditional beliefs and practices, often as a reaction to what they consider moral decline or religious dilution due to modernity.
