authority on

Adım Adım Çözüm

1
Analyze the sentence context to determine the relationship between the noun 'authority' and the field of study 'volcanic seismology'.
The sentence describes Dr. Rostova's high level of expertise in a scientific field, not her power or jurisdiction over a group.
Choosing the correct preposition depends on whether 'authority' refers to power/control or expertise.
2
Evaluate the idiomatic prepositions that pair with 'authority'.
The idiom 'authority on' indicates expertise in a subject, whereas 'authority over' indicates power/control, and 'authority to' indicates permission to act.
This step determines which prepositional collocation is correct for the intended meaning.
3
Select the option that correctly uses the preposition denoting expertise.
The option containing 'authority on' is the correct idiomatic match for the context.
This provides the proper idiomatic correction for the underlined portion.
