1. What would be the best piece of evidence to support the following claim “Plants grow faster when they have access to sunlight”

2. 
   

   1. The plants in the dark grew 5 inches in one week

   2. The plants in sunlight grew 7 inches more than the plants in the dark

   3. The plants grown in sunlight had tastier fruits that the ones grown in the dark

   4. The fruit of the plants grown in the dark were 1% heavier than the fruit of the plants grown in sunlight.
