Rearrange the sentence parts to form a logical passage:
P. New samples are logged with precise timestamps and locations.
Q. Environmental DNA (eDNA) is collected from soil and water samples.
R. Sequencing machines then extract biodiversity signatures.
S. Results feed into conservation models predicting species distribution.
Show answer & explanation
Correct answer: B
Explanation
Correct Answer: QPRS
Explanation
• Q introduces the primary subject and the initial step of the scientific process: collecting Environmental DNA (eDNA) from soil and water samples.
• P naturally follows by describing what is done immediately after the samples are taken—logging them with precise timestamps and locations.
• R presents the laboratory analysis stage, indicated by the transitional word then ("Sequencing machines then extract biodiversity signatures").
• S provides the final outcome and real-world application, explaining how the findings are used to predict species distribution in conservation models.
Logical Order: Collection (Q) → Logging (P) → Sequencing (R) → Application (S)
