The answer is "more" because they said both more and frequent which are synonyms
Last year my family and I went on a camping trip to the Mississippi river. It was intended to be a peaceful getaway but quickly turned into quite an adventure. On our way to the campground a small dog ran out from behind a tree and ran right across the road. Thankfully my dad quickly swerved leaving it unharmed. That dog did a dangerous maneuver and he didn’t even bark! At our campsite was a basket full of squirrel treats. They really pushed feeding them. They wanted the squirrels to get as much food and grow so the dragons can eat them. The dragons are giant! And they live in big dark caves. We wanted to visit one so we did. We saved a lot of time by riding our bikes instead of walking. When we got there we were trembling. What human being goes to a dragons cave? We were terrified. The ground around us started shaking. I opened my eyes to my mom shaking me to wake up. We were about to miss the plane!
