Answer:
The correct answer is H) pucker.
Step-by-step explanation:
The sentence uses the word "sour" to describe the lemonade and "pucker" to describe Florence's reaction to it. Puckering is a common physical reaction to sourness, so this is an example of an appropriate word choice. The other options, F) prize, G) purse, and J) pennant, do not relate to sourness or puckering.
