Final answer:
Kelly is likely to mention engaging activities or memorable experiences from her day at the beach, such as playing in the sand or the water, interactions with her mother, and sensory experiences.
Step-by-step explanation:
When Kelly's father asks her what she did that day at the beach, considering her age, she is most likely to talk about the activities that were most engaging or memorable to her. These could include playing in the sand, collecting shells, wading or swimming in the water, building sandcastles, or any interactions she might have had with the sea creatures. Given children's tendency to focus on sensory experiences and the examples provided in the passages, she may also refer to a meaningful interaction with her mother, such as a moment of affection, or share a simple yet vivid description of something she observed or felt, like the texture of the sand or the temperature of the water.
