    The Trail Map (story)

    [1] The county park had asked for a new trail map, and Zee volunteered to draw it. [2] On the first Saturday, Zee walked the whole loop with a notebook, counting steps between the signposts. [3] Back home, Zee sketched the trail in pencil and showed it to the ranger.

    [4] “It looks great,” the ranger said, “but the creek bridge is missing.” [5] Zee frowned, because the old bridge had washed out in the spring, and the new footpath crossed on stepping stones. [6] A map that showed a bridge would send hikers toward a crossing that no longer existed. [7] Zee decided to return on Sunday and check the stepping stones in person.

    [8] The stones were wider apart than Zee remembered, and a family with a stroller turned back at the water's edge. [9] That evening, Zee added a small note beside the creek: “Stepping stones, not for strollers.” [10] Zee also drew a second path that circled around to the parking lot, though it added half a mile to the loop.

    [11] When the ranger saw the finished map, the ranger studied the longer path for a long moment. [12] Then the ranger smiled and pinned the map to the board at the trailhead.

  2. Kira chose sentences 3 and 6 for “Zee wanted the map to match what was really on the trail”, but only one of them proves it. Which pair keeps that one and swaps the other?

  4. Monarchs on the Move (article)

    [1] Each fall, millions of monarch butterflies in eastern North America fly south to the mountains of central Mexico, and some travel more than 2,000 miles. [2] A monarch weighs less than a paperclip, so the trip seems impossible for such a fragile insect.

    [3] The butterflies that make the journey are not the same ones that flew north in spring. [4] Most monarchs live just two to six weeks as adults, but the final generation of the summer is different. [5] These butterflies can live for about eight months, which gives them time to reach Mexico, rest through the winter, and begin the return trip.

    [6] Scientists believe monarchs steer by the sun, adjusting their direction as the sun moves across the sky. [7] At night they rest together in trees, and on cold mornings they must warm their wings before flying.

    [8] In spring, the survivors head north and lay eggs on milkweed, the one kind of plant that monarch caterpillars can eat. [9] Their offspring continue the trip over several generations, and by late summer a new generation is ready to fly south. [10] Because milkweed is disappearing from many fields, groups across the continent now plant it along roadsides and in gardens.

  8. The Substitute Drummer (story)

    [1] When the regular drummer of the town band had to travel for a family visit, Milo, who had played in the school percussion group, was asked to take the part for the harvest parade. [2] Milo agreed at once, but the sheet music had more tempo changes than anything Milo had practiced before.

    [3] For three nights, Milo tapped the rhythms on a pillow with pencils and marked each change in red ink. [4] On the fourth night, Milo asked the band director to explain one section that still confused the whole group. [5] The director played it slowly, and Milo wrote the counts above the staff in neat numbers.

    [6] On parade day, trumpets glittered in the sun and the street was packed with families holding flags. [7] Milo began the opening beat so firmly that the walkers in the first row fell into step. [8] During the second song, a sticky drumhead slowed Milo's right hand, but the rhythm held. [9] When the band reached the town square, the regular drummer was waiting, back from the trip, with a big grin.

    [10] Milo handed over the sticks, then pointed at the red marks in the music and said, “These helped.” [11] The regular drummer laughed, flipped to the last page, and pinned a small paper star above the final measure.

  9. Tala reads between the lines: “Milo's preparation kept the beat steady on parade day, even when the drumhead stuck”. Which two sentences, read together, prove it?

  11. How Ships Cross the Panama Canal (article)

    [1] Before the Panama Canal opened in 1914, a ship traveling from the Atlantic Ocean to the Pacific had to sail the long way around South America. [2] The canal cut thousands of miles from that voyage, but engineers faced a problem: the land between the oceans is hilly, and the middle of the route is higher than the sea.

    [3] Their answer was a system of locks. [4] A lock is a long chamber with huge gates at each end. [5] When a ship enters, the gates close behind it, and water flows into the chamber, lifting the ship like an elevator. [6] Starting from the Atlantic side, a ship climbs in three steps to Gatun Lake, which sits about 85 feet above sea level.

    [7] The water for the locks does not come from pumps. [8] It flows downhill from the lake through large tunnels, using gravity alone. [9] When a ship goes down toward the other ocean, the water drains out of the chamber the same way.

    [10] Ships cross the lake under their own power, and electric locomotives called mules guide them through the narrow lock chambers. [11] A full trip takes about ten hours, far less time than the long voyage around South America.

  12. Esme reads between the lines: “The height of Gatun Lake is what lets the locks fill without pumps”. Which two sentences, read together, prove it?
