Skill 4: IMPLIED DETAIL QUESTIONS

The number of rings in a tree can be used to determine how old a tree really is. Each year a tree produces a ring that is composed of one light-colored wide band and one dark-colored narrow band. The wider band is produced during the spring and early summer when tree stem cells grow rapidly and become larger. The narrower band is produced in fall and early winter when cell growth is much slower and cells do not get very large. No cells are produced during the harsh winter and summer months.

This question asks about the age of a tree with 100 wide bands and 100 narrow bands. The passage does not tell the age of a tree with 100 wide and narrow bands, but it does indicate that….wide band and one.....narrow band are produced each year From this, you can draw the conclusion that a tree with 100 wide and narrow bands is 100 years, or a century, old. The best answer to this question is therefore answer A..
