Information and Ideas practice question

To estimate the age of the yew, the surveyors did not core it: the trunk is hollow, so a core would tell them nothing. Instead they measured its girth and compared it with yews of known planting date across the county, a method that gives a range rather than a year but that, for hollow trees, is the only one available.

According to the text, why did the surveyors measure the yew's girth instead of taking a core?

  1. A. The trunk is hollow, so a core would provide no information.Correct
  2. B. Coring is illegal.
  3. C. Girth gives an exact planting year.
  4. D. The yew was too tall to core.

Answer: A. The trunk is hollow, so a core would provide no information.

A hollow trunk defeats coring.

Why the other answers are wrong

Not mentioned.
C. Girth gives an exact planting year.

D. The yew was too tall to core.
