Final answer:
Fluency involves reading or speaking smoothly with comprehension, which is true. Fluency is enhanced by practice and self-awareness, avoiding verbal fillers, and complemented by effective gestures and facial expressions. Additionally, fluid intelligence is linked to problem-solving skills, and one manifest function of schools is teaching reading and writing.
Step-by-step explanation:
The statement that fluency is the ability to read smoothly, without hesitation, and with comprehension is true. Fluency in both reading and speaking is about the flow and efficacy of language use. When speaking fluently, it is not about the speed but rather the continuity and clarity of speech that makes the communication effective.
For example, practicing speech and being self-aware can significantly improve fluency and reduce the use of verbal fillers like 'um', 'ah', and 'like', which can otherwise detract from the fluency. Additionally, in person or online, gestures and facial expressions can enhance the delivery of a script by adding emotion and emphasis to the speech, further supporting fluent communication.
As for the additional questions provided, the answer to the question regarding fluid intelligence is 'd. being able to see complex relationships and solve problems.' This speaks to the cognitive abilities that allow an individual to reason and think flexibly. The manifest function of schools, another concept within sociology and education, chiefly pertains to 'b. Learning to read and write', which are explicit and recognized objectives of educational systems.
