这个句子有二处错误。

1 现在完成时使用没有道理，为错误。应改为一般现在时：This school break is unique for this generation, ... (说话时，学校还没有开学，即 school break在说话时仍然存在者。)

2 the questions now are  when is it safe for kids to go back to school.

这个问句形式错误。要么when从句改用正常语序，从句为间接疑问句：the questions now are  when it is safe for kids to go back to school. 要么用自由直接引语：the questions now are: When is it safe for kids to go back to school?
