Question

PLEASE HELP?!?!

Answer 1

The sentence tjat effectively combines the clauses to make clause one dependent of clause two is the third option: While Padmi looks frantically for her pen, her sister calmly writes with it.

The clause "while Padmi looks frantically for her pen" could not stand alone as it cannot convey a total thought. I would not make sense, hence it depends of the second clause which conveys the total meaning of the statement. The word while, which is a conjuction, provides as the clue to spot the dependent clause.

Dependent clause :a clause that cannot form a separate sentence but can form a sentence when joined with a main clause

Answer 2

While Padmi looks frantically for her pen, her sister calmly writes with it. "While Padmi looks frantically for her pen," cannot stand alone. Using it in "While Padmi looks frantically for her pen, her sister calmly writes with it." makes it dependent on the second part of the sentence.
