Horse, cattle, goats, sheep, and chicken manures were the common types of fertilizers used to grow big, healthy plants like corn, tomatoes, and squash and pumpkins in those days. Manure is the waste or "poop" of the animal and it is rich in nitrogen that helps plant grow well. Manure is used today by many people who do organic gardening. A non-organic nitrogen fertilizer is NH4NO3 (ammonium noitrate) which supplies nitrogen for plant growth.

12. D. A fern is not a tree, the other three: spruce, fir and pine are common evergreens used as Christmas trees.

13. A. Real candles were used on some Christmas trees way before there was any electricity. However, a real burning candle can cause dangerous fires quite easily and  real lighted candles should NEVER be used for a Christmas tree lighting.

15. A. Snow is crystalline or frozen water.

16. B. Each snowflake is a very unique crystalline pattern. Some have said that no two snowflakes are alike, but since no one has ever analyzed all the snowflakes this cannot be proven. nevertheless, snow crystals are very varied and very different and if you looked at a few hundred, or thousand, or maybe even a million, snowflakes no two would be exactly alike.
