Theme or tone because in the theme the Narrative speaks like what is happened and more but in tone you will know when he speaks like one.
The answer would be D.
In the story, it shows that he leaned his basic numbers by helping his father count and sort the rocks, hinting that he didn’t have the time to go to school and had to learn things on his own, in his own way :)
These are some examples of famous inventions that really improved our quality of life. Hope you find them useful!
1. Light bulbs
This invention allows us to see and work in the dark. Long ago before lights are invented, we cannot do much during night time, even if you light up a candle, it won't last long and they may catch other things on fire. Light bulbs can be used for a long time, and they're a lot safer and there's a lot more we can do in our lives in nighttime nowadays. Even though yes LEDs are taking over, but before LED is invented, light bulbs are certainly important.
2. Steam Trains
This improves the transportation. Before steam trains are invented, people usually travel either by walking or they ride animals such as horses. Steam trains can give us a fast way to go to another location.
3. Radio
Radio gives us a simple and fast way to send messages and spread information to far locations. This is very useful especially back then, where people can spread information during wars or other emergency situations. We can contact others faster.
