Question

even if possible

帮帮忙分析英语语法结构
however,even if prediction becomes possible,people who live in areas where earthquakes are a common occurrence will still have to do their best to prevent disasters by building structures that are resistant to ground movement and by being personally prepared.

Answer 1

本句主语是people,谓语主体部分是will have to do their best (to prevent disasters)
even if引导的是让步从句（即便地震变得可以预测）
who引导的自然是个定语从句(生活在地震多发区的人)
两个by引导方式状语,说明如何prevent disasters.第一个意为“修建抗地动房屋”,第二个意为“自身做好心理准备”
