Answer:
Yes.
Step-by-step explanation:
The main concern of the writer - or the topic sentence - which is stated in the first sentence, is that keeping his or her mind when writing is not easy when they are staying at their grandmother's cottage. We are then treated with several sentences explaining why it is hard, with various distractions that the author willingly or unwittingly found themselves in.
The final sentence supports this topic sentence since what the author is writing in her or his typewriter remains discontinued since they are too preoccupied with other things to finish their work.
