Answer:
Phones, Gas, and Fresh Food
Explanation:
I think the increase in the prices of these things is thanks to:
Phones: More advanced technology, but it's harder to obtain the materials needed
Gas: Foreign oil is becoming more expensive as other countries capitalize the industry
Fresh Food: Food that is produced in factories is cheaper, and less and less people are farmers. Also, farming is difficult, and producing good crops for millions of people is difficult.
