I want to know the answer to the following question:
Which interstate directly connects the east with the Arizona Sun Corridor and Imperial County?
All the background I'm provided with is that "This includes Interstate 5, which runs south to Tijuana and north to Los Angeles; Interstate 8, which runs east to Imperial County and the Arizona Sun Corridor; Interstate 15, which runs northeast through the Inland Empire to Las Vegas and Salt Lake City; and Interstate 805, which splits from I-5 near the Mexican border and rejoins I-5 at Sorrento Valley.". Is that enough to answer the question?
Answer: yes
