Praxis Core Integration of Knowledge and Ideas Summary

Only this finding measures flexibility before and after, and compares students who stretched with students who did not. That directly tests the claim.

Wrong choices

• "Many students say they enjoy stretching before class.": Enjoying stretching says nothing about flexibility.
• "Professional athletes often stretch before games.": What athletes do is not evidence that it works.
• "Some students who stretched daily also played soccer.": This does not measure flexibility and mixes in another activity.
• "A daily stretching routine takes about ten minutes.": The time it takes does not show any result.

Passage 1 says gardens teach science through planting and measuring. Passage 2 says teachers use gardens for science lessons. Science is the shared point.

Wrong choices

• "cost too much to maintain": Only Passage 2 mentions cost, and it still says gardens offer real benefits.
• "make children more willing to eat vegetables": Only Passage 2 mentions tasting vegetables.
• "should replace classroom lessons": Neither passage says gardens should replace lessons.
• "are useful only in the spring": Neither passage mentions seasons.

Three bottles seen once is not enough evidence to show "huge amounts" every day. The conclusion goes far beyond the evidence.

Wrong choices

• "It quotes an expert who is not qualified.": No expert is quoted.
• "It uses too many statistics to make its point.": No statistics are given.
• "It does not say what the student wants.": The student clearly asks for a recycling program.
• "It gives equal attention to both sides of the issue.": Only one side is presented.

Snacks and longer hours started in the same month. Attendance went up, but the data cannot tell which change caused it.

Wrong choices

• "The snacks were the only reason more students came.": Two changes happened at the same time, so the snacks cannot be singled out.
• "The longer hours had no effect on attendance.": The data cannot separate the effect of the longer hours.
• "Attendance will keep rising every month.": The data cover only one month after the change.
• "Students came mainly to eat rather than to study.": The data do not show why students came.

Compare the four numbers: 420, 510, 480, and 300. The largest is 510, in October.

Wrong choices

• "November": November had 480, which is less than October's 510.
• "September": September had 420.
• "December": December had the fewest, 300.
• "September and November (tied)": September (420) and November (480) are not equal, and neither is the highest.

The largest number in the list is 1.1 inches, recorded on Wednesday. Check the units: all values are in inches, so they can be compared directly.

Wrong choices

• "Saturday": Saturday had 0.7 inch, less than Wednesday's 1.1.
• "Thursday": Thursday had 0.4 inch.
• "Sunday": Sunday had 0.3 inch.
• "Monday": Monday had 0.2 inch.

1. Half of 200 is 100.
2. 120 parents chose text messages.
3. 120 is more than 100, so more than half chose text.

Check: 120 + 50 + 30 = 200, matching the total surveyed.

Wrong choices

• "Most parents preferred email.": Only 50 of 200 preferred email.
• "More parents preferred printed notes than email.": Printed notes (30) had fewer than email (50).
• "Fewer than 100 parents preferred text messages.": 120 parents preferred text messages, which is more than 100.
• "Equal numbers of parents preferred email and printed notes.": Email had 50 and printed notes had 30, which are not equal.

Both passages agree there is no tailpipe exhaust. Passage 2 adds that the overall benefit depends on the power source, such as coal.

Wrong choices

• "Passage 2 says electric cars produce tailpipe exhaust.": Passage 2 agrees that electric cars produce no tailpipe exhaust.
• "Passage 2 says electric cars are worse than gasoline cars everywhere.": Passage 2 says the benefit is smaller in coal regions, not that the cars are worse everywhere.
• "Passage 2 says coal power is cleaner than other power sources.": Passage 2 suggests coal reduces the benefit, which means it is not cleaner.
• "Passage 2 says cities should ban electric cars.": Passage 2 says nothing about banning electric cars.

1. Route 3 had 3,050 riders.
2. Route 1 had 2,400 riders.
3. 3,050 - 2,400 = 650.

Check: 2,400 + 650 = 3,050.

Wrong choices

• "600": 600 is the difference between Route 1 and Route 4 (2,400 - 1,800).
• "1,250": 1,250 is the difference between Route 3 and Route 4.
• "850": 850 does not match any pair of routes; recheck the subtraction.
• "1,900": 1,900 is the difference between Route 3 and Route 2.

The claim is about pedestrian safety. Records of pedestrian accidents at that corner directly show whether there is a safety problem.

Wrong choices

• "The name of the company that would install the signal": The installer's name does not show whether the corner is unsafe.
• "The number of restaurants on Main Street": Restaurants do not show anything about pedestrian safety.
• "The year Fifth Street was first paved": The street's history does not relate to current safety.
• "The color the signal poles would be painted": Paint color has nothing to do with safety.
