When an independent clause is combined with a dependent clause it forms a complex sentence
true
false

That is true! The independent clause can stand by itself, but if a dependent clause is introduced, it forms a complex sentence.

Example: Because I was running late for work, I received a warning

Hope I have helped!

imparadis't in one anothers arms  

the happier eden, shall enjoy their fill  

of bliss on bliss, while i to hell am thrust,  

where neither joy nor love, but fierce desire,  

among our other torments not the least,  

still unfulfill'd with pain of longing pines;  

yet let me not forget what i have gain'd  

from their own mouths; all is not theirs it seems:  

one fatal tree there stands of knowledge call'd,  

forbidden them to taste: knowledge forbidd'n?  

suspicious, reasonless. why should their lord  

envie them that? can it be sin to know,

i think the answer would mist likely be an adjective clause, because unhappy is an adjective.
