Suppose That G1 Represents the Ratio of Year 2 GDP $\sqrt { g 1 \times g 2 }$

Multiple Choice

Suppose that g1 represents the ratio of year 2 GDP to year 1 GDP, both valued at year 1 prices. Suppose that g2 represents the ratio of year 2 GDP to year 1 GDP, both valued at year 2 prices.
The ratio of chain-weighted year 2 GDP to chain-weighted year 1 GDP equals

A) $\sqrt { g 1 \times g 2 }$ .
B) $\sqrt { g 1 / g 1 }$ .
C) $( g 1 + g 2 ) / 2$ .
D) $( \sqrt { g 1 } + \sqrt { g 2 } ) / 2$ .
E) $( g 1 \times g 2 ) / 2$ .
