How was Einstein in speaking during childhood?

Correct answer: He started speaking late

The governing detail is Einstein’s delayed speech in early childhood. The biographical account says that he did not begin speaking as early as most children, and his family was concerned about this unusual development. Therefore option B is correct. The question refers to when he began to speak, not to the speed or amount of his later conversation. Option A changes delayed speech into rapid speech, while options C and D suggest constant public or private talking, neither of which is the reported fact. This detail should not be used to judge intelligence: a late start in speaking does not prevent a child from developing exceptional understanding and creativity later.
