Question

what concerns did shopkeepers have about the sudden end of penny production?
a they were worried about how to handle transactions without enough pennies.
b they were worried about the cost of producing other coins.
c they were worried about the environmental impact of producing pennies.
d they were concerned about the historical value of pennies.

Explanation:

Shopkeepers' main concern with the end of penny production would relate to daily transactions. Option A addresses handling transactions without enough pennies, which is practical for shopkeepers. Option B is about producing other coins (not their concern), C about environmental impact (more of a broader issue, not shopkeepers' primary worry), and D about historical value (not a shopkeeper's main concern). So A is correct.

Answer:

A. They were worried about how to handle transactions without enough pennies.
