The tulu, a popular ornamental plant, does not
reproduce naturally, and is only bred and sold by
specialized horticultural companies. Unfortunately,
the tulu is easily devastated by a contagious fungal
rot. The government ministry plans to reassure
worried gardeners by requiring all tulu plants to be
tested for fungal rot before being sold. However,
infected plants less than 30 weeks old have generally
not built up enough fungal rot in their systems to be
detected reliably. And many tulu plants are sold
before they are 24 weeks old.
Which of the following, if performed by the
government ministry, could logically be expected to
overcome the problem with their plan to test for the
fungal rot?
(A) Releasing a general announcement that tulu
plants less than 30 weeks old cannot be
effectively tested for fungal rot
(B) Requiring all tulu plants less than 30 weeks old
to be labeled as such
(C) Researching possible ways to test tulu plants
less than 24 weeks old for fungal rot
(D) Ensuring that tulu plants not be sold before they
are 30 weeks old
(E) Quarantining all tulu plants from horticultural
companies at which any case of fungal rot has
been detected until those
