This is true regardless of age.
People will be alert and receptive 【C2】_____ they are faced with information that 【C3】_____ them to think about things they are interested in.

Many experts are so 【C7】_____ of the benefits of challenging the brain 【C8】_____ they are putting the theory to 【C9】_____ in their own lives.

【C7】
选项
A、believed
B、convinced
C、supposed
D、concerned
答案
B
解析
考查动词语义。下文提到了很多专家向大脑提出挑战这一事实,表明他们相信挑战大脑有好处,convinced“确信的”,符合文意,故选B。believe也表“相信”,但用过去分词形式时表示的是被动语态,不是可作表语的形容词性质,所以排除A。
