House's revision of his theory puts more emphasis on the need for leaders to foster a. concrete rewards b. stress management techniques c. intrinsic motivation d. an external locus of control e. personal growth in management knowledge

The answer is "c. intrinsic motivation".

Intrinsic motivation alludes to conduct that is driven by interior rewards. As such, the motivation to take part in a conduct emerges from inside the individual since it is normally fulfilling to you. This diverges from extrinsic motivation, which includes participating in a conduct so as to acquire external rewards or stay away from discipline.  

Intrinsic motivation happens when we act with no conspicuous external rewards. We basically appreciate an action or consider it to be a chance to investigate, learn, and complete our possibilities.

the correct answer is economics is a game without winners or losers.

unlike sports or games economic is a game without losers or winner rather it is a game where everyone wins. parties of business doing businesses exchange money with each other and hence exchange is done on the basis of goods. one party takes the goods and other sales it so there is winner on both sides. each party values more highly the good it gets than the good it gives up. both sides exchange only because both intend to increase their value. so there is no concept of lose or win.
