Change the following from active to passive:
Citizens can rarely access archived stamps without clearance.

The correct option is: Archived stamps can rarely be accessed without clearance.

To convert an active voice sentence to passive voice, follow these steps:

1. Identify the subject, verb, and object of the active sentence:
- Subject: Citizens
- Modal Verb + Adverb + Main Verb: can rarely access
- Object: archived stamps
- Prepositional Phrase / Rest of the sentence: without clearance

2. Move the object to the subject position:
The object "Archived stamps" becomes the new subject of the passive sentence.

3. Change the verb structure to passive voice:
For modal verbs (such as can), the passive voice structure is:

Modal Verb + Adverb + be + Past Participle of Main Verb

4. Combine the elements:
Combining the new subject, passive verb phrase, and the remaining modifier gives:
"Archived stamps can rarely be accessed without clearance."
