Interstellar

I watched "Interstellar" today. Honestly, I couldn't understand it well but I was into the movie. I couldn't stop watching it even though I don't like watching long movies.
I have no knowledge of physics so the last part of this movie was so new for me. Maybe I should have listened more during high school physics.

Writing: graph analysis

This line graph illustrates the change in sales for four different online shops (Shop A, Shop B, Shop C, and Shop D) in 2010.
There are gaps in the growth in sales among the four shops. For example, while the sales at shop C increased throughout the year, the sales for shop A and shop D declined. For shop B, they remained stable.
Shop C showed a dramatic change in sales from January to December. At the beginning of the year, the number of monthly (?) sales was only 100, which was the smallest. However, it gradually started to rise and, in July, surpassed the sales for Shop D, which was ranked third prior to that. By the end of the year, the number of sales was over 400, which was the second largest of the four shops.
Shop A also showed an impressive change in sales. In January, the number of sales was 500. Then, it increased to almost 700 but decreased sharply. After that, it kept rising with a small amount of fluctuation and reached a peak of 700 in October. However, it declined again for two months after that, and finally, it fell to the number of sales that it had in January.
