Question

monte is a three - year - old boy recently diagnosed with autism. he appears completely unresponsive to his parents and shows no indication of any language development. monte seems disinterested in communication of any kind and has significant rituals such as lining up his toys and realigning them every few minutes. he becomes hysterical if anyone interrupts his ritualistic activity. on an iq assessment designed for very young children, montes score was extremely low. his prognosis is poor primarily because of
his lack of language acquisition and low iq.
his low iq and early age of onset.
the early age of onset and lack of language acquisition.
his ritualistic behavior and disinterest in his parents.

Explanation:

Poor prognosis in autism is strongly linked to two key factors here: severe lack of language development by age 3, which is critical for communication and intervention progress, and an extremely low IQ score, which is associated with limited adaptive functioning and response to support. Early onset alone is not the primary driver, and ritualistic behavior/parental disinterest are symptoms rather than core predictors of poor long-term outcomes.

Answer:

A. his lack of language acquisition and low IQ.
