Yes, this is true.
Some people don't really need to work (for example they have inherited a lot of money) but they work nonetheless because they seek social support or want to make a contribution to the world (such as working in the NGOs - organisations focused on improving life of others).
Answer:
<em>Working Together • Federal, state, and local governments work together to build roads. City governments cooperate on common interests. Serving the Public • Federal government gives grants-in-aid and block grants to state and local governments. State and local governments assure citizens' quality of life.</em>
<h3><em>Purpose: Local governments serve the purpose of making communities a better place to live. They do that by passing ordinances, or regulations that follow state laws.</em></h3><h3>

When burning, Yes.
A normal fire in a steel-frame building can soften the structure to the point of collapse.
Building laws / regulations require that all the structural steelwork is either covered in a protective coating (such as intumescent paint) or boxed in with fire-resistant plaster, so the fire can be extinguished before the building is weakened - or at least give people time to get out.
If that coating or plaster is damaged by impact or an explosion, the steel is exposed and the building can collapse relatively quickly.
(The common intumescent coatings just look like paint until exposed to fire, so the steelwork may appear to have no particular protection - but it always does).

See the images below - small buildings with steel-frame roofs after fires; you can see the amount of "sagging" and distortion on structures that have no particularly high loads.
These have burned long enough to destroy any protection, or they did not have any as the structure does not support occupied space.
