R48 EOC #14 says:

Based on the data in Exhibit 2, which fund is most sensitive to the combined surprises in inflation and GDP growth in Exhibit 3?

Relavent info is A: b for inflation is .5 and b for GDP is 1.0

C: b for inflation is 1.0 and b for GDP is 1.1

Then actual - expected inflation is 0.2 and actual - expected GDP is -0.5

So they say A is more sensitive to the combined surprise because its ((.5 * 2%) + (1.0*-0.5%) = -0.5%

and C: ((1 * 0.2%) + (1.1*-0.5%) = -0.55%

So if inflation surprse was 10%, obiously C would be a higher value, so how is that not more sensative?

Thanks.
