Question

which sentence uses the underlined vocabulary word incorrectly? he gazed apathetically and duly out the window at the cloudy sky. the runt of a litter often suffers from infirmities and sometimes doesnt survive. due to the imminent tornado, the family hurried to the storm shelter.

Explanation:

1. Analyze the first sentence: "duly" means in a proper or appropriate manner. Gazing apathetically and duly is a contradiction in terms as apathetic implies lack of interest while duly implies proper - ness. This usage is incorrect.
2. Analyze the second sentence: "infirmities" means physical or mental weaknesses. A runt of a litter being weak and sometimes not surviving makes sense. This usage is correct.
3. Analyze the third sentence: "imminent" means about to happen. A family hurrying to a storm - shelter due to an approaching tornado is a correct usage.

Answer:

He gazed apathetically and duly out the window at the cloudy sky.
