Answer:
1. Year 1 cost of goods sold
2. Year 2 cost of goods sold
4. Year 2 beginning inventory
Explanation:
If year 1's ending inventory is wrong, the beginning inventory of year 2 will also be wrong (they are the same).
Cost of goods sold = cost of goods available for sale - ending inventory, so COGS for year 1 will be affected since ending inventory is wrong
Cost of goods available for sale = beginning inventory + purchases - ending inventory. Since beginning inventory year 2 is wrong, the cost of goods available for sale will also be wrong, as well as COGS
