A request for proposal for a specific program may require the company to review the bids to not only examine their feasibility but also the health of the bidding company and the ability of the bidder to actually do what is proposed.
The most obvious reason for using spatial imagery in metaphors is that the language of the primary processes (e.g., dreams) is spatial imagery. This can explain everything, but is trivial: it is always true, and you cannot make meaningful distinctions with it in a text or in changing contexts.
The simplest form of imagery to recognise is when something or someone is compared to something else, with the purpose of establishing some parallel between the two. Images of this kind frequently concern qualities like beauty, speed, force, power and natural and animal traits. Example. He ran as fast as a leopard.
