Step 1: Read the cartoon:
The cartoon shows a bicycle labelled CHINA. The front wheel carries the old socialist emblem and the rear wheel carries a dollar sign.
A cycle moves because of the push on the rear wheel. Here the rear wheel is marked with a dollar sign.
Step 2: Understand the idea:
The dollar stands for the US economy. China opened its economy to foreign trade and investment after 1978, and the US became one of its biggest trade partners.
So the US economy has a strong pull on how China grows.
Step 3: Check the options:
(A) The influence of the US economy on China: this matches the cartoon. Right.
(B) Fifty percent partnership: the two wheels are not shown as equal partners of a deal. Wrong.
(C) Dependence of China on US economy: this is too strong, since China has its own large economy. Wrong.
(D) Economic aid to China by US: trade is shown, not aid. Wrong.
Final Answer:
The dollar shows the influence of the US economy on China. The correct option is (A).
