A lichen is not one organism. It is a fungus and an alga living as one body.
The fungus provides the structure and holds water. The alga photosynthesises and makes sugar. Separated, the fungus starves and the alga dries out.
Because it needs no soil, a lichen can grow on bare rock, on gravestones and on the roofs of cars that have not moved for a decade.
Lichens grow extremely slowly — some crustose species less than a millimetre a year. Scientists use that rate to date rock surfaces, a method called lichenometry.
Lichens also absorb whatever is in the air. Where the air is dirty, they disappear, which makes them a living measure of pollution.
1. What is the author's purpose, and how do you know?
2. The text says lichens are a living measure of pollution. What reason is given?
2.Read the text, then answer the questions.
What a Coral Reef Is
A coral reef looks like rock and is built by animals.
A coral polyp is a soft creature the size of a pinhead. It draws calcium from the sea water and builds a hard cup around itself. Millions of polyps, cup upon cup, become a reef.
Inside each polyp live tiny algae. The algae make food from sunlight and pass most of it to the polyp. In exchange they get shelter and the polyp's waste. Neither could build a reef alone.
When the water gets too warm, the polyps expel the algae. Without them the coral turns white and starves. That is what bleaching means.
A reef takes centuries to build and can bleach in a single hot summer.
1. What is the author's purpose, and how do you know?
2. The text says neither organism could build a reef alone. What evidence supports that?

Answer key — Which Evidence Supports What
Set 1. Prints on its own sheet.
1.1. To explain what a lichen is and why it is useful to scientists — the last two paragraphs are both uses. 2. They absorb whatever is in the air, so they disappear where the air is dirty.
2.1. To explain what a reef is and why it is fragile — the last line makes the contrast explicit. 2. The algae make the food; the polyp makes the cup and gives them shelter.
Questions about Which Evidence Supports What
What does the Which Evidence Supports What worksheet cover?
It practises matching a piece of evidence to its claim — 2 questions for Grade 4, all on Common Core RI.4.8: Explain which reasons and evidence hold up each of the author's points. The instruction to pupils is “Read the text, then answer the questions”, and the answer key follows on the next sheet.

25 — one per pupil, and all 25 ask different questions. Set 1 downloads the whole class as a single PDF. Every version is fixed to its own address, so a sheet printed today holds the same problems when you reopen it next week.
