A to-infinitive clause can express purpose: We record stories to preserve them. It can follow a noun or adjective: a place to visit; ready to help. After an ordinal, superlative or only, it can modify a noun: the first student to arrive. Negation is not to: We agreed not to touch the artefacts. Match the implied actor and do not use for + bare infinitive to express purpose.
Topic preview: A removable interpretation display is a practical way to preserve heritage while improving access. That is an interesting suggestion; could you explain how the audio version would be checked? I would invite a local specialist to verify dates and let residents review attributed memories before publication. We should preserve uncertainty honestly rather than make every story sound certain. For example, the display could distinguish a dated museum record from a resident’s recollection. Both may be useful, but they are different kinds of evidence. A large-print guide and a quiet route would let visitors choose how to learn. Nobody should drill into an old wall or handle a fragile object simply to improve a school presentation. Our proposal should support professional conservation rather than replace it. Which part of the display would you ask a specialist to review first?
Follow-up: Why make the display removable?
Response: It can be updated without drilling into historic material, provided its placement is approved.
