acceptable if the sediments are also identified by particle size acceptable if the factors used for the classification are given unacceptable because others would not understand the classification system unacceptable because this is not the way scientists usually classify sediments
I gave my students this multiple choice question: Sediments are generally classified by particle size. A student would like to classify sediments by their source. Which statement best describes this alternate classification?

Only one answer is correct among these 4 choices:
- acceptable if the sediments are also identified by particle size
- acceptable if the factors used for the classification are given
- unacceptable because others would not understand the classification system
- unacceptable because this is not the way scientists usually classify sediments

Could you tell me which one is correct?

acceptable if the factors used for the classification are given
