I have two questions about this analogy from an SSAT practice test:
Silk is to worm as
A. honey is to bee
B. corn is to pop
C. bread is to wheat
D. egg is to chicken
E. frog is to croak
Their explanation is:
By now, you have seen several types of analogies involving objects or individuals and activities. There is the object-to-activity analogy (chisel is to carve), as well as the individual-to-activity analogy (tourist is to sightsee). The sequence presented here is another variation, this time involving insects. To answer this question correctly, you will need to know that worm and silk appear in the stem [I don't understand what that means] because silk is produced by a species of worm. Similarly, honey is produced by bees.
I don't get why A is better than D. What gives A the edge over D? Their so-called explanation doesn't clarify that. What am I missing here?
