{"id":"praxis-core-free","timeLimitSec":420,"questions":[{"id":"pxf-01","section":"reading","q":"Community gardens in many cities began as a way to turn empty lots into food plots. People who study them report other effects as well: neighbors who garden together tend to know one another by name, and some neighborhoods see less litter near active gardens. For many members, the vegetables have become a bonus rather than the main reason to take part.\n\nWhich statement best expresses the main idea of the passage?","options":["Most community gardens are built on lots that cities sell to residents.","Gardening reduces litter in every city that tries it.","Community gardens now offer social benefits beyond growing food.","Members grow vegetables mainly to save money on groceries."],"answer":2,"explain":"The passage moves from food plots to the 'other effects' (neighbors knowing each other, less litter) and ends by calling the vegetables a bonus. The main idea is the wider social benefit. 'Every city' overstates the passage, and nothing is said about selling lots or saving money."},{"id":"pxf-02","section":"reading","q":"The new principal's first decision was a modest one: she moved the morning announcements from the loudspeaker to the classrooms, where teachers read them aloud. Yet the change was telling. It showed that she wanted students to hear school news from the adults who knew them best.\n\nAs used in the passage, \"telling\" most nearly means","options":["revealing","talkative","harmful","ordinary"],"answer":0,"explain":"The next sentence explains what the change 'showed' about the principal, so 'telling' means revealing. It does not mean talkative here, and 'ordinary' contradicts the point that the change said something important."},{"id":"pxf-03","section":"writing","q":"Which sentence is written correctly?","options":["Each of the students have turned in a permission slip.","Each of the students has turned in a permission slip.","Each of the student has turned in a permission slip.","Each of the students have turn in a permission slip."],"answer":1,"explain":"The subject is 'Each', which is singular, so the verb is 'has'. The phrase 'of the students' does not change the subject, and 'of the student' should be plural after 'each of'."},{"id":"pxf-04","section":"math","q":"A school orders 3 boxes of markers for every 4 classrooms. How many boxes does it need for 28 classrooms?","options":["21","24","37","12"],"answer":0,"explain":"Set up the ratio: 3/4 = x/28. Then x = 28 × 3 ÷ 4 = 84 ÷ 4 = 21 boxes."},{"id":"pxf-05","section":"math","q":"A student's quiz scores are 82, 90, 75, 88 and 85. What is the mean (average) score?","options":["85","83","86","84"],"answer":3,"explain":"Add the scores: 82 + 90 + 75 + 88 + 85 = 420. Divide by the number of scores: 420 ÷ 5 = 84. (85 is the median, the middle score when sorted.)"}]}
