It is important for readers to check for evidence in a text to determine if the information is believable.
Use the sentence to answer the question.
Wildfires are essential to the survival of certain plant species.
Which piece of information provides the best evidence to support the idea in the sentence?
(1 point)
• Some plants have adapted to live through wildfires.
• Some plants need wildfires in order to complete a regular life cycle.
• Wildfires help get rid of dead plants like old leaves and logs.
• Ecosystems benefit from the plants that grow after a wildfire.
The information that provides the best evidence to support the idea in the sentence is:
"Some plants need wildfires in order to complete a regular life cycle."
Use the sentence to answer the question.
At a low intensity, flames can clean up debris and underbrush on the forest floor, add nutrients to the soil, and open up space to let sunlight through to the ground.
Which topic sentence does the evidence best support?
(1 point)
High temperatures and low rainfall turn plants into the perfect fuel for
wildfires.
Wildfires that burn near communities can become dangerous if they grow
out of control.
• Climate change has left some ecosystems more susceptible to wildfires.
• Wildfires play an important part in maintaining healthy ecosystems.
The evidence best supports the topic sentence: "Wildfires play an important part in maintaining healthy ecosystems."
Which option best describes evidence in a text? (1 point)
