Directions: An introductory sentence for a brief summary of the passage is provided below. Complete the summary by selecting the THREE answer choices that express the most important ideas in the passage. Some sentences do not belong in the summary because they express ideas that are not presented in the passage or are minor ideas in the passage.
Write your answer choices in the spaces where they belong. You can either write the letter of your answer choice or you can copy the sentence.
Plants need to absorb certain minerals from the soil in adequate quantities for normal growth and development.
Answer Choices
[A]Some plants can tolerate comparatively low levels of certain minerals, but such plants are of little use for recycling nutrients back into depleted soils.
[B]When plants do not absorb sufficient amounts of essential minerals, characteristic abnormalities result.
[C]Mineral deficiencies in many plants can be cured by misting their roots with a nutrient solution or by transferring the plants to a soilless nutrient solution.
[D]Though beneficial in lower levels, high levels of salts, other minerals, and heavy metals can be harmful to plants.
[E]Because high concentrations of sodium chloride and other salts limit growth in most plants, much research has been done in an effort to develop salt-tolerant agricultural crops.
[F]Some plants are able to accumulate extremely high levels of certain minerals and thus can be used to clean up soils contaminated with toxic levels of these minerals.
