Substitutes are pairs of products : A. positive cross-price elasticity of demand B. negative cross-price elasticity of demand C. positive income elasticity of demand D. negative income elasticity of demand E. positive price elasticity of demand

A. positive cross-price elasticity of demand

Explanation:

For substitute goods we always have a positive cross-price elasticity of demand. The cross elasticity of demand for substitute goods is always positive because the demand for one good increases when the price for the substitute good increases.

For example, if the price of a

brand of beverage increases, the quantity demanded for a substitute beverage increases, this happens because consumers will quickly switch to a less expensive yet substitutable alternative. In the cross elasticity of demand formulae both the price and product are positive.

the correct answer is 2.

a slump in geology means a mass movement process of slope failure. a mass of rock or unconsolidated material drops along a slip surface. in other words, rock layers move a short distance down the slope. the slump block is an intact block (2), without any landslide material.

in this image, 1 is the surface of rapture (scarp), 2 the slump block, 3 main scarp (crown), 4 base of rapture with debris flow.

slumps are caused by clear cutting on unstable soils and the sagging of earth, in coastal areas they are due to wave infiltration.
