Question

Concentrate,decorate,suggest,nice odd man out

Answer 1

The concentrate is the work doing without any oscillation and delay;

the decoration is to do work with some equipment to attract some people, suggest is the thing that we prefer someone to do work or points, nice is said by all when the art or work was done well.

Therefore, the odd one is decoration, because all the three are doing their work without fail, preferring their work and getting a good name for their work but decoration is to attract by work.
