What is wrong with the following sentence?
He wants to become a doctor his family insist that he study law.
1. It is a run-on
2 It is a comma splice
3 It is a dangler
4. It is a fragment

Hello fully,

This is a run-on sentence.

There are two independent clauses in this sentence, which are not
properly joined.  The first independent clause is "He wants to become
a doctor."  The second independent clause is "his family insist that
he study law."  (Incidentally, there is another grammatical error in
this sentence.  The second clause should be "his family insists that
he study law.")

The error can be corrected "by adding a conjunction with a comma" or
"by separating the two clauses with a semicolon."

In this case, the error can be corrected by rewriting the sentence as:

He wants to become a doctor, but his family insists that he study law.

 or

He wants to become a doctor; his family insists that he study law.

"his family insist ..."

In British English, sometimes it is acceptable to use the plural form
of the verb with a singular subject that represents a group,
suggesting that the various individuals in the group are acting.

But don't ask me for another example.  Maybe "Parliament are debating
...", on the logical feeling that a singular entity cannot debate.
