To approach this question, I will evaluate each language milestone option for a child around 20 months.
Option 1: "She understands metaphor and satire." At 20 months, children are just beginning to acquire language and do not typically grasp abstract linguistic devices like metaphor or satire. Understanding metaphor and satire requires advanced symbolic language skills and more developed cognitive processing than is typical at this age, so this statement is unlikely.
Option 2: "She uses an average of 200 words." By 20 months, a child’s vocab usually ranges much lower than 200 words. Most children this age have a vocabulary of a few dozen to perhaps around 50 words, with rapid growth occurring closer to 2 years. Therefore saying an average of 200 words at 20 months overstates typical development.
Option 3: "She uses a few prepositions." Early prepositions (such as in, on, under) begin to appear a bit later, often around 24 months or beyond, when children start combining words and using relational terms. At 20 months, use of prepositions is still limited, so this statement could be plausible but may not be a dominant milestone yet.
Option 4: "She asks yes and no questions." While children begin to imitate and briefly use yes/no intonation in early speech, forming true yes/no questions with appropriate syntax is generally a more advanced skill that develops a little later, not typically at 20 months.
In summarizing, each option reflects a milestone expectation that has some tension with typical 20-month development: metaphor/satire is unlikely, 200 words is implausibly high, prepositions may be emerging but are not yet prominent, and yes/no question formation is more advanced than the simplest 20-month speech. The provided correct option in many educational resources aligns with the idea that a 20-month-old has a relatively small but meaningful vocabulary, often around a couple dozen to a few dozen words, with rapid but modest growth, rather than reaching 200 words. The evaluation of the remaining options shows they either overstate or misrepresent the typical capabilities at this age, or require later developmental stages to be reliably present.
Note: Because developmental milestones can vary among individual children, these interpretations reflect common-age benchmarks used in many language development charts rather than universal absolutes. The key idea is that 20 months is characterized more by growing word use than by mastery of complex syntax or high word counts, which supports the idea that the 200-word figure is atypical for this age group.
