I NEED HELP PLS Chieko is doing an experiment with a water clock. She fills a 2-liter soda bottle with water and marks the water level. She puts two tiny pinholes in the base of the bottle. Water seeps out. She checks the time against her watch. After an hour, she marks the new water level. She repeats this process until the water is all gone. Chieko made six hour marks on the bottle, representing the passage of six hours. How can Chieko test her water clock to see if the timing is accurate?
Group of answer choices

Repeat the experiment using a better watch

Repeat the experiment using less water in the bottle

Repeat the experiment using a kitchen timer set to go off each hour

Repeat the experiment using the same amount of water and the same watch
