Concept:The blank requires an adverb that describes a habitual or usual behavior, contrasting with today's exception.
Explanation:The sentence says the brother is usually punctual, but today he is late.
The correct word must mean "under normal circumstances" or "as a rule".
Let us examine each option:
• Option A:
"Normatively" relates to standards or norms; it does not fit the context of habit.
• Option B:
"Primarily" means mainly or chiefly; it does not convey usualness.
• Option C:
"Normally" means usually or as a regular practice.
• Option D:
"Basically" refers to fundamental aspects; it is unsuitable here.
Only "normally" correctly expresses that the brother's punctuality is typical, making the exception notable.
Thus, the most appropriate choice is
"normally".
Answer:The correct answer is
"normally".
Complete sentence: My brother is
normally punctual, but he is late today.
