问题如下：
Suppose a painting is produced and sold in 2010 for £5,000. The expenses involved in producing the painting amounted to £2,000. According to the sum-of-value-added method of calculating GDP, the value added by the final step of creating the painting was:
选项：
A.£2,000.
B.£3,000.
C.£5,000.
解释：
B is correct.
This is the value added by the artist: £5,000 – £2,000 = £3,000.
考点：GDP的计算
解析：本题比较常规，直接用最终产品的价值减去上一步商品的价值即可。
£5,000 – £2,000 = £3,000.
啥呀这是，最终商品的价格不就已经算过了成本吗，为啥还要重复剔除？
