A? i feel like is the answer but im not positive lol sorry.
The imagery is “the sun shone brightly on them half the day” because its giving a better idea of what whatever they are talking about is like in the day
You could use a topic such as "2 common breeds of dogs and their characteristics" or "How to raise a tomato plant from seed" or "Critical tips for surviving in the wilderness", etc. (Basically, you need to do it on a topic you are familiar with and interested in)
Please give more information and I’ll try to help the best I can.
