Final answer:
The best example of maturation that must precede learning is learning a language before learning to read, as fundamental language skills naturally develop before and support the ability to read.
Step-by-step explanation:
The scenario that best exemplifies maturation that must PRECEDE learning to observe a developmental change is B) Learning a language before learning to read. This is because in the sequence of language development, fundamental language skills such as understanding and speaking come before the ability to read. The development of oral language capabilities is a natural process that generally precedes and aids in the learning of reading, which is a more complex skill built upon the foundation of spoken language. Maturation involves reaching certain physical and cognitive developmental milestones that allow for subsequent learning to take place. For example, stage theories of development indicate that children follow a universal sequence of milestones, such as babbling before speaking words. These sequences of development must occur to support the learning of more complex skills that come later, such as reading.
