In this lesson: Assess agreement between datasets and distinguish a model match from proof.
Grammar in this story: Passive form for a research requirement
Direct measurements of particles and light in the water are needed
Are needed is a present passive form. It puts the required measurements first rather than naming the people who need them.
Your turn
Why should researchers obtain direct water measurements even though their models support the plastic explanation?
See one possible answer
The datasets differ in the size and extent of the changes, and a match with a model does not prove the cause. Measuring particles and light directly would test the proposed link.
Your answer can be different. Give a reason and use your own words.
