The Indian plate's 24 movement is not new.
答案：(C) northward
文章前段已說明印度板塊是往北推擠喜馬拉雅山（pushes northward），故此處為 northward movement（向北移動）；wayward 是「任性的」不表方向，downward（向下）、outward（向外）都與文中所述方向不符。
答對率 35%。
四個選項都以 -ward 結尾，你大概以為是在比四個方向。但 wayward 根本不是方向詞，它的意思是「任性的、難以駕馭的」（a wayward child 難管教的孩子）——這是埋得最深的陷阱。
本句自己沒有任何方向訊息，要回到文章開頭：as it pushes northward against the Himalayas（印度正往北推擠喜馬拉雅山）。
northward／southward／upward／downward／inward／outward／forward／backward／homeward，全是「朝某方向」；只有 wayward 是例外。
move northward（向北移動）、an upward／downward trend（上升／下降趨勢）、a wayward child（叛逆難管的孩子）。
India is shrinking. A new analysis of satellite-based data has given precisely the rate 21 which the country is losing size as it pushes northward against the Himalayas. According to the analysis, the 22 between India's southern and northern tips shrinks by 2 cm every year. As India's size decreases, the thickness of the Himalayas increases. 23 the shrinking continues, India will disappear in 200 million years. There would only be a vast mountain range along the southern coast of China.
The Indian plate's 24 movement is not new. However, this cannot be treated as a trivial finding in science. A movement of 25 a few millimeters (mm) of the earth's crust is a sign of possible earthquakes. Such dangers are now obvious in India, where the movement of the plate continues.
