Answer:

This may seem illogical, but with critical thinking:

1. In 2021, the global median age is 30 years old. Since I am 13 and 8 months old, my hypothetical older baby brother is 17 years and 4 months older. However, since my birthday is adjusted to July, almost half a year has to be added, and since Christmas is on October, 2 months have to be deducted. That is:

17 years and 4 months - 2 months + 6 months = 17 years and 8 months. That means my brother is 17 years and 8 months older, approximately 31 years old.

2. There is only one place I believe we could shop at school: the canteen. Since most canteens sell school supplies, we can buy crayons there. I am more likely to buy a blue crayon.

Now, warm colors (such as red and yellow) symbolize passion and joy. Cool colors symbolize sadness.

Since warm colors symbolize joy, and joyful people tell the truth, warm colors are true. Cool colors symbolize sadness, and sad people hide the truth, cool colors are false.

My blue crayon is a cool color, thus, the answer is false.
