Praxis Core Key Ideas and Details Summary

Every sentence in the passage explains how the waggle dance tells other bees the direction and distance of food. A main idea must cover the whole passage, and this choice does.

Wrong choices

• "The length of a waggle run shows how sweet the flowers are.": The passage says the length shows how far away the flowers are, not how sweet they are.
• "Honeybees can only find flowers that are close to the hive.": The passage never limits bees to nearby flowers; the dance tells them the distance.
• "Honeybees always fly straight toward the sun when they leave the hive.": The dance gives a direction in relation to the sun; it does not say bees always fly toward it.
• "Young worker bees learn to dance by watching older bees for weeks.": The passage says nothing about how bees learn the dance.

Neighbors "who had never spoken before" began trading tomatoes and recipes. This supports the conclusion that the garden brought neighbors together.

Wrong choices

• "The garden will close next year because it has run out of space.": Families asked to add plots; nothing says the garden will close.
• "Most residents did not want the garden at first.": The passage never describes residents opposing the garden.
• "The tool shed was the most popular part of the garden.": The shed is mentioned only once, with no sign that it was the most popular part.
• "The garden produced more food than any other garden in the city.": The passage makes no comparison with other gardens in the city.

From the first sentence to the last, the passage explains that sleep strengthens what people learned. The final sentence states the point directly: sleep is an important part of learning.

Wrong choices

• "how to fall asleep faster before a test": The passage does not give advice on falling asleep.
• "why people need more sleep as they get older": Age is never mentioned in the passage.
• "why some people dream about lists of words": The passage mentions remembering word lists, not dreaming about them.
• "how the body repairs its muscles during sleep": The passage is about the brain and memory, not muscles.

A good summary includes the main points: the program, the improvement, and the plan to expand. Only this choice includes all three without adding anything new.

Wrong choices

• "Reading aloud in front of the class is the best way to raise reading levels.": Reading in front of the class was a side effect, not the method that was tested.
• "Teachers at Lincoln Elementary did not want volunteers in their classrooms.": Teachers were unsure the program would work; they did not reject the volunteers.
• "Second graders learn more when they read alone than with an adult.": The passage describes children reading with adults, and it worked.
• "The school will end the program because it needs too many volunteers.": The school plans to recruit more volunteers, not to end the program.

The passage moves from the supporters' view, to research showing little benefit for young children but more for older students, to schools changing their practice. The correct choice covers all of this.

Wrong choices

• "Homework has no effect on students in any grade.": The passage says the link is stronger for upper grades, so it does have some effect.
• "Parents want more homework so they can see what their children learn.": This is one argument of supporters, not the central idea.
• "Homework should be banned at every grade level.": The passage never calls for a ban; schools replaced worksheets with reading.
• "Reading for twenty minutes is harder for children than completing worksheets.": The passage does not compare how hard the two tasks are.

The last sentence begins "As a result" and states that farm products from the Midwest flowed east. This detail is stated directly in the passage.

Wrong choices

• "Wagon travel became faster and cheaper than before.": The passage says wagon travel was slow and expensive; the canal offered a cheaper choice instead.
• "Mules replaced boats as the main way to move goods.": The mules pulled the boats; they did not replace them.
• "Lake Erie was connected to the Pacific Ocean.": The canal created a route to New York City and the Atlantic side, not to the Pacific.
• "Midwestern farmers stopped selling goods in the East.": The passage says the opposite: Midwestern products flowed east.

The last sentence says a book more than 30 days overdue "is treated as lost" and must be returned or paid for before more items can be checked out.

Wrong choices

• "The borrower must pay a small fine for each day.": The passage says the library no longer charges fines.
• "The book is automatically renewed for another month.": Nothing in the passage mentions automatic renewal.
• "The borrower loses library privileges permanently.": The borrower can borrow again after returning or replacing the book, so the loss is not permanent.
• "The library sends the bill to a collection agency.": The passage does not mention a collection agency.

The last sentence says that if many students missed the same question, she reteaches that idea in the next class. That is how she uses the cards.

Wrong choices

• "To give students a grade for the whole lesson": The passage never says the cards are graded.
• "To let students suggest topics for future lessons": Students answer questions about the lesson; they do not suggest topics.
• "To take attendance at the end of the day": The cards check learning, not attendance.
• "To send a report home to parents each evening": She sorts the cards herself; nothing is sent home.

Every new rule limits water use, and the council mentions the low reservoir. Together these clues show the goal is to use less water.

Wrong choices

• "The town reservoir will be completely empty by June.": The reservoir is low, but the passage never says it will run dry.
• "Watering lawns during the day is against state law.": The rule comes from the town council; state law is not mentioned.
• "Restaurants in Dry Creek will close during June.": Restaurants are asked to serve water on request, not to close.
• "Residents use more water in restaurants than at home.": The passage gives no figures comparing water use in restaurants and homes.

Flooding happens when too much water rushes into storm drains. The detail about trees catching rainwater, which reduces that rush, is the only one about water.

Wrong choices

• "A large shade tree can lower the air temperature beneath it.": Cooler air is a benefit, but it has nothing to do with flooding.
• "City trees provide benefits that are easy to overlook.": This is the general opening claim, not a detail about flooding.
• "Tree-lined streets have been linked to slower driving speeds.": Slower driving is about traffic safety, not water.
• "Shade trees are most helpful on summer afternoons.": This is about heat, not rain or flooding.
