Question: Place the following sentences in the appropriate column. A river travels steeply downhill. The water swirls. Water becomes foamy and white. The river is swift and challenging. Passengers do not listen to their guide. Cause Effect Water moves fast. Boulders and rocks are in the river. The water moves rapidly. Everyone must join in paddling. The adventure becomes a disaster.

1. **State the problem:** We need to classify each sentence as either a cause or an effect. 2. **Define cause and effect:** - A *cause* is why something happens. - An *effect* is what happens as a result. 3. **Analyze each sentence:** - "A river travels steeply downhill." → Cause (the slope causes the river to flow fast) - "The water swirls." → Effect (swirling is caused by obstacles or fast flow) - "Water becomes foamy and white." → Effect (foam forms due to turbulence) - "The river is swift and challenging." → Effect (result of steep slope and obstacles) - "Passengers do not listen to their guide." → Cause (their behavior can cause problems) - "Water moves fast." → Effect (result of steep slope) - "Boulders and rocks are in the river." → Cause (obstacles cause turbulence) - "The water moves rapidly." → Effect (result of slope and obstacles) - "Everyone must join in paddling." → Effect (response to swift river) - "The adventure becomes a disaster." → Effect (result of passengers not listening and river conditions) 4. **Final classification:** **Cause:** - A river travels steeply downhill. - Passengers do not listen to their guide. - Boulders and rocks are in the river. **Effect:** - The water swirls. - Water becomes foamy and white. - The river is swift and challenging. - Water moves fast. - The water moves rapidly. - Everyone must join in paddling. - The adventure becomes a disaster. This classification helps understand the relationship between events and their outcomes.
