Final answer:
Part 1905 of OSHA concerns modifications to and revocation of State plans, and it deals with general provisions rather than specific industries like Construction, Agriculture, Maritime, or Mining.
Step-by-step explanation:
The subject matter of Part 1905 is not directly related to Construction, Agriculture, Maritime, or Mining. Instead, Part 1905 deals with modifications to and revocation of approved State plans and addresses issues such as variances from OSHA standards, limitations of certain regulations, rules of practice for administrative proceedings, and other general provisions. However, if asked to categorize broadly, Part 1905 would be most related to General Industry rather than any specific industry like Construction, Agriculture, Maritime, or Mining.
