Task: Question Answering
Input (English): Passage: San Diego (3-4) lost their third straight game, 7-6 on the road to the Cleveland Browns (2-6). After blowing second-half leads the past two games in consecutive losses, the Chargers never led in this game. Both offenses struggled with wind blowing to more than 40&#160;mph (64&#160;km/h) and rain falling throughout the entire game. Rivers was 18 of 34 for 154 yards, but had a touchdown pass dropped by Meachem in the third quarter. With the Chargers forced to run because of the bad weather, Mathews ran 24 times for 95 yards. The Browns' Trent Richardson ran for 122 yards and a touchdown. It was the second game of the year the Chargers did not score an offensive touchdown. The last time San Diego failed to score a touchdown in two or more games was in 2000, when it occurred three times. With the Broncos' win that same week, the Chargers fell into a second place tie with the Raiders in the AFC West. 
Question: How many passes did Rivers complete? 
Answer type: Number 
Output (English): 18.
