Question

correct the text by inserting one comma.
arvind mahankali finished third in the 2011 and 2012 scripps national spelling bee competitions and he finished first in 2013.

Explanation:

To correct the text, we need to insert a comma to separate the two independent clauses. The first clause is about finishing third in 2011 and 2012, and the second is about finishing first in 2013. A comma should be placed before "and he" to properly connect these two independent clauses.

Answer:

Arvind Mahankali finished third in the 2011 and 2012 Scripps National Spelling Bee competitions, and he finished first in 2013.
