我也要先謝謝你提問,讓我有動力去搞清楚這個觀念。

double (adj)

double (predet) →predeterminter 前置限定詞
if something is double the amount or size of anotherthing, it is twice as large
例句 The offer was to start a new research laboratory at

double (v)
when something doubles or when you double it, it becomes twice as great in number, amount, or size.
例句 The number of managers must double to 100 within 3 years.
The program will double the amount of money available to hekp pay for child care.
(看了三種字典,double用作動詞時,都是主動,沒有被動,例:OG72,這是一項規則嗎?)

from Longman Dictionary Online
double (predeterminer)
twice as big, twice as much, or twice as many
例句We'll need
double this amount for eight people.
The value of the house is
double what it was.
另外,twice作adv用也是有,但是"好像"只用於bent double這個片語之上,我想double的主流用法僅需討論adj / v / predet 這三者即可。所以og11e 128說不用double來修飾produce是可以理解的。不過這一題中(A)produce double the apple如果視為v+predet+det+N我覺得是結構上是沒有問題的,不過後面that it has 就完全是錯的。
回到og 11e 第4題,跟隨pufa的意思,這題double是作predet即限定詞之用,完全合情合理!

補充:相對於double的字,沒錯,就是half ~
OG 59:
In 1978 only half the women granted child support by a court......
from Collins Cobuild advanced version
half (predet) is also a predeterminer
例:They had only received half the money promised.
