Which sentence pattern is different from the other three?
a) until my cousin bought the tickets, i never even considered going to the concert.
b) after the music stopped, evan finally understood why i loved the cellist's music.
c) as soon as i heard alisa weilerstein play her cello, i fell in love with classical music.
d) evan stopped and asked for directions to the concert hall because his gps was not working properly.

Sentence D is different from the others.

The other options (A-C) begin with a dependent clause and a comma - option D does not.

Definitely D. if you read them carefully they're are a few differences.

Option A,B, and C is wrong because there is one independent clause and one dependent even though they are all structure correctly without a conjunction.

They also all have commas and the last option is two independent clauses
