Krashen predicts that certain structures are acquired late; which example best illustrates such a late-acquired structure?

• A. The son enjoys riding on the carabao
• B. I am going home now
• C. They have finished early
• D. She eats lunch

Answer: (B)

Late-acquired structures are those forms learners typically master later because they add aspect and require extra auxiliary help. The sentence I am going home now uses the present continuous: am going. This construction combines the auxiliary be with the -ing form to show an action in progress. That extra layer—auxiliary plus an ongoing aspect—tends to develop later for many learners, making this a good example of a late-acquired pattern. The other examples lean on simpler patterns: a verb followed by a gerund after enjoy is a common, early-learned structure; a simple present statement like eats lunch is basic; and even though have finished is a more advanced tense, the progressive form here best illustrates the idea of delayed acquisition Krashen highlights because of its ongoing aspect.
