safety procedures the only way a person
licensed as an electrician in Parker County
can have learned those procedures?

requirement for becoming a licensed
electrician in Parker County but not for
graduating from the college in computer
technology?

Technical College who are not majoring in

在PC要电工第一件事情是需要完成某一门可能，而PC技术学校的所有PT专业学生都必须完成同一门课程才能毕业。所以，学校PT专业毕业的学生都可以成为电工。

两个条件看似紧密，其实毫无联系。只要是通过了该课程的人都是具备成为电工资格的，无论是否是学生，或者毕业与否。而通过该课程的学生能否顺利毕业也是不可知的。但是，毕业的学生肯定通过了这门课程，这是必然的，那么毕业生能否成为电工就要看成为电工是否还有其他的条件，如果没有的话，结论就是成立的。

B. Do all students majoring in computer technology who complete the course in electrical safety procedures at ParkerCounty Technical College eventually graduate?
所以了解学校PT专业学生是否毕业对于他们能否成为电工没有任何限制。即使不毕业，通过了那门课程就可以了。

D. Is a period of practical apprenticeship a requirement for becoming a licensed electrician in Parker County but not for graduating from the college in computer technology?
那么，全部选项中，只有D选项在其中提到了附加条件的问题，是不是需要做一段时间的学徒才能成为电工。

3# keyuke 这是个问句~你再读一遍看看这个问句是在强调什么?
就是在强调毕业生是不是也要参加这个practical apprenticeship啊~

但是D选项是说"requirement of apprenticeship...but not for graduating from the college"
这个requirement只是对非该大学毕业生的，他们参不参加和毕业生参不参加没有关系啊，毕业生该拿执照就拿执照，感觉还是无法evaluate the question

文章说没有完成a certain course in electrical safety procedures的话不能成为an electrician，注意这是必要条件不是充分条件哦。不是说只要完成了这个course就成为了electrician~D选项正确：它指出这些graduate是不是和其他非graduate一样需要在成为electrician之前参加一个practical apprenticeship（如果需要的话就refute了原文的结论，不需要的话就support了原文的结论）。B选项不正确：这些学生完成了这个course之后毕没毕业跟结论一点关系也没有啊~毕了业的就be licensed as an electrician，没毕业的不颁发就okay了呗（如果原文结论成立的话）。
