Read the answer and explanation

Guiding future monitoring research. The second paragraph uses could for future monitoring research and rejects an established timetable.

Clue: Modelling points to hotter, deeper magma disturbing a shallow reservoir. The pattern could guide future monitoring research, but it is not an established timetable for predicting eruptions.

Read and understand · 2/2What evidence was observed directly in the study?

Read the answer and explanation

A recurring chemical signature in crystals. The first paragraph reports the identified signature.

Clue: A study published on November 9 identified a recurring chemical signature in small plagioclase crystals from Andean volcanoes, Queensland researchers reported.

Grammar in this story: A tentative interpretation

Modelling points to

Points to indicates support for an interpretation rather than direct observation of every proposed process.

Your turn

Explain why the finding is promising without claiming it predicts eruption dates.

See one possible answer

The crystals show a recurring chemical pattern, and modelling links it to deeper magma disturbing a shallow reservoir. It could guide monitoring research, but it is not an established eruption timetable.
