Synthesis practice questions

Synthesis questions ask you to combine information from notes or sources into one accurate statement. Every part of the answer has to be supported by the material given, and a single unsupported detail is enough to make a choice wrong.

Synthesis questions

Pick an answer before you look. Tapping a choice shows which one was right and opens the worked explanation, and a miss is remembered so Weak Skills can replay that skill. It stays in this browser.

    Notes for an article state that a wetland restoration began in 2019, native plants were added in 2020, and bird surveys recorded 14 more species by 2023. Which sentence most effectively summarizes the notes?

    Show the answer and explanation

    Answer: A restoration begun in 2019 added native plants the next year and was followed by an increase in recorded bird species by 2023.

    This choice accurately joins the timing and the reported result without inventing a cause, a comparison of survey methods, or a starting species count.

    Notes: A neighborhood association planted 60 street trees in 2020, and 54 were alive in 2024. A nearby association planted 45 trees the same year, and 27 were alive in 2024. The first association watered new trees weekly for two summers. The student wants to emphasize the difference in survival between the two groups. Which choice best uses the notes?

    Show the answer and explanation

    Answer: Of the trees planted in 2020, 54 of 60 survived where volunteers watered weekly, compared with 27 of 45 where they did not.

    Only this choice states both survival figures side by side, which is what emphasizing a difference requires. The others report a single fact and invite no comparison.

    Notes: A repair cafe opened in 2021. Volunteers fixed 410 items in its first year and 980 in 2024. About 70 percent of items brought in are repaired successfully. The student wants to emphasize the growth in the cafe's activity. Which choice best uses the notes?

    Show the answer and explanation

    Answer: Volunteers at the repair cafe fixed 410 items in 2021 and 980 in 2024.

    Growth is a change over time, so the choice must carry both figures. The success rate, the opening year, and a single year's total each state one fact and show no change.

    Notes: A footpath was resurfaced in 2022. Before resurfacing, 200 walkers used it weekly. After, 340 used it weekly. The path is 2 kilometers long. The student wants to emphasize the increase in use. Which choice best uses the notes?

    Show the answer and explanation

    Answer: Weekly use of the footpath rose from 200 walkers to 340 after it was resurfaced in 2022.

    An increase needs both figures. The others give a length, a single current figure, or a reason the notes do not contain.

    Notes: A community choir formed in 2016. It had 18 members then and 74 now. It rehearses weekly. It has performed at 40 events. The student wants to emphasize the choir's growth in membership. Which choice best uses the notes?

    Show the answer and explanation

    Answer: The choir has grown from 18 members at its founding in 2016 to 74 today.

    Growth is a change, so both membership figures must appear. A single current number shows size, not growth.

    Notes: A repair shop opened in 2019. It repaired 240 items in its first year and 1,100 in 2024. It employs four people. Around 15 percent of items brought in cannot be repaired. The student wants to emphasize the growth in the shop's workload. Which choice best uses the notes?

    Show the answer and explanation

    Answer: Repairs rose from 240 in the shop's first year to 1,100 in 2024.

    Growth in workload needs both figures. Staffing, failure rate and opening year are true and describe something else.

    While writing about a 1908 photograph of a market square, a student has taken these notes: - The photograph shows 40 stalls. - A council register for 1908 lists 52 licensed traders. - The photograph was taken on a Tuesday. - The market's main day was Saturday. The student wants to explain why the photograph shows fewer stalls than the register would suggest. Which choice best uses the notes to do this?

    Show the answer and explanation

    Answer: Taken on a Tuesday rather than the market's main day of Saturday, the photograph shows only 40 of the 52 licensed traders.

    Only one choice puts the day beside the shortfall, which is what turns two facts into an explanation. The first states the discrepancy without accounting for it, and the last two report one side of it.

    While researching a lighthouse, a student has taken these notes: - The lighthouse was automated in 1989. - Before automation it was staffed by three keepers. - It now has no keepers. - Its light is still visible 26 miles out to sea. The student wants to make the point that automation changed who worked there without changing what the building does. Which choice best accomplishes this goal?

    Show the answer and explanation

    Answer: Automated in 1989, the lighthouse lost its three keepers but still shows a light visible 26 miles out to sea.

    Making the point requires both halves in one sentence: the staffing that ended and the function that did not. The other choices carry one half each, and a change needs two sides to be visible.

    While researching a village school, a student has taken these notes: - The school opened in 1874. - It had 96 pupils in 1900. - It has 41 pupils now. - It is the only school within nine miles. The student wants to explain why the school stays open despite falling numbers. Which choice best accomplishes this goal?

    Show the answer and explanation

    Answer: Though numbers have fallen from 96 to 41, it remains the only school within nine miles.

    The explanation lies in the note the other choices leave out: distance. Falling numbers alone would be a reason to close, and it is the absence of an alternative that answers the question asked.

    While writing about a closed footbridge, a student has taken these notes: - The bridge closed for repair in March. - The detour adds 1.2 km to the journey. - Around 400 people crossed daily before the closure. - Repairs are due to finish in October. The student wants to convey the cumulative cost of the closure to the people affected. Which choice best accomplishes this goal?

    Show the answer and explanation

    Answer: For seven months, 400 crossings a day have each become 1.2 km longer.

    A cumulative cost needs the three quantities multiplied together in the reader's head: how long, how many people, how much further. Each other choice supplies one of the three and leaves the total invisible.

    While writing about a rescued cinema, a student has taken these notes: - The cinema opened in 1929 and closed in 1997. - It was bought by a community trust in 2011. - Restoration cost 2.1 million pounds. - 1,400 people hold shares in the trust. The student wants to emphasize that the rescue was collective rather than the work of one buyer. Which choice best accomplishes this goal?

    Show the answer and explanation

    Answer: The 2.1 million pound restoration was funded by a trust with 1,400 shareholders.

    Collective effort shows in the number of people set against the size of the sum. Naming the trust alone leaves it indistinguishable from a single institutional buyer.

    While writing about a restored steam pump, a student has taken these notes: - The pump drained 1,200 acres of fen from 1831. - It was replaced by a diesel engine in 1941. - Volunteers restored it between 1998 and 2016. - It is now run four times a year. The student wants to convey that the pump has been preserved as a demonstration rather than returned to service. Which choice best accomplishes this goal?

    Show the answer and explanation

    Answer: Restored over eighteen years, the pump that once drained 1,200 acres now runs four times a year.

    The contrast between what it used to do and how seldom it now runs is what marks it as a demonstration. Any single note leaves that contrast unmade.

    While writing about a bird hide, a student has taken these notes: - The hide was built by volunteers in 1997. - It overlooks a lagoon created by gravel extraction. - 63 species have been recorded from it. - The lagoon was a working quarry until 1989. The student wants to convey that the site's value is recent and accidental. Which choice best accomplishes this goal?

    Show the answer and explanation

    Answer: A gravel quarry worked until 1989 is now a lagoon from which 63 species have been recorded.

    "Recent and accidental" needs the industrial past and the wildlife present in one sentence: nobody dug the quarry to make a lagoon. Any single note gives one half and leaves the point unmade.

    While researching a canal restoration, a student has taken these notes: - The canal closed to traffic in 1944. - Restoration began in 1998. - 11 of the canal's 17 locks have been rebuilt. - Volunteers have given about 90,000 hours. The student wants to convey that the work is substantial but unfinished. Which choice best accomplishes this goal?

    Show the answer and explanation

    Answer: Some 90,000 volunteer hours since 1998 have rebuilt 11 of the canal's 17 locks.

    "Substantial but unfinished" needs the effort and the fraction in the same sentence: 90,000 hours is the scale and 11 of 17 is the shortfall. The last choice carries the shortfall alone and the third the scale alone.

  15. 15SynthesisChallenge

    While researching a peat bog, a student has taken these notes: - Drainage ditches were cut across the bog in the 1960s. - Blocking those ditches began in 2015. - The water table has risen by 22 cm since. - Sphagnum moss now covers 40 percent of the site, up from 5 percent. The student wants to show that one intervention produced two connected effects. Which choice best accomplishes this goal?

    Show the answer and explanation

    Answer: Blocking the 1960s ditches has lifted the water table by 22 cm, and moss cover has gone from 5 to 40 percent.

    Two connected effects need the cause and both effects in one sentence, which only one choice manages. The others give the cause alone or one effect alone, and neither shape can show a connection.
