请数学老师讲解 一下图片题
另外我之前问的一道题 您没有解答清楚b选项
A certain list consists of 3 different numbers. Does the median of the 3 numbers equal the average (arithmetic mean) of the 3 numbers?
(1)The range of the 3 numbers is equal to twice the difference between the greatest number and the median.
(2)The sum of the 3 numbers is equal to 3 times one of the numbers.

提问:
请问这题中“explore”的动发者为什么是“Lina”呢?我在读A选项时总觉得选项中explore的动发者是“A group of films” 因为觉得explore前面的主体是“A group of films”, 而 in 1970 和 Lina 都是修饰films的。
