Analyze the sentence structure

The sentence is: "During the scenic tour of the national park, the cascading waterfall was photographed repeatedly."
The main subject is "the cascading waterfall" and the verb phrase is "was photographed".

Identify the action and receiver

The action is photographing. The subject ("the cascading waterfall") is receiving the action rather than performing it. The agent performing the action is unstated.

Determine the grammatical structure

Using our understanding of Verb Tenses, we look at the construction "was photographed". This is formed by the auxiliary verb "to be" (was) followed by the past participle of the main verb (photographed). This specific construction indicates the passive voice.

Evaluate the given options

• Active voice: Incorrect, because the subject is not performing the action.
• Passive voice: Correct, as the subject receives the action.
• Future tense: Incorrect, "was" is past tense.
• Present tense: Incorrect, "was" is past tense.
