Answer 2

Answer:

The diary was almost incapable of being destroyed. The papers were impossible to tear and felt like elastic. The diary was still in a good condition after being bitten by a dog and dropped into fire. The diary kept changing the colour of the ink. It had been green, turned to red, blue and then yellow. These were the two peculiarities of the diary.
