Practice 27 Verb tense, form, and consistency questions in the app
On the ACT English test, Verb tense, form, and consistency covers choosing the verb that fits a sentence and keeping that tense aligned with nearby sentences.
A student has to decide whether an action is ongoing, finished, or being recalled from an earlier moment, then pick the matching form. Items usually ask which option is most grammatically acceptable in context, or which wording most clearly shows an idea as it stood at an earlier point in the passage.
Choices typically show one verb in competing tenses or forms. The common trap is a polished option that shifts time without a reason in the passage.
Pick an answer to see whether it is right — nothing is saved, and nothing needs an account.
Hydrologist Celia Mendez wanted to learn where rainwater traveled after disappearing into a gravel basin beside a community garden. During a dry week, her team installed clear sampling tubes at three points downhill. Each morning, Mendez checks1 the water level in every tube and recorded the result on a field map. The first readings revealed one problem, the underground water moved too slowly to trace by level alone.2
Mendez therefore mixed a harmless fluorescent dye into a measured bucket of water. The team poured the mixture into the basin at nine o'clock and covered the opening so another shower could not dilute it. By noon, the dye concentration in the lowest tube had risen3 from zero to four parts per billion. Mendez compared two channels, one ran beneath compact clay, and the other crossed loose gravel.4 The gravel channel carried the brighter sample, suggesting that its larger spaces allowed faster movement. Team members photographed each tube against a white card so faint color changes could be compared later.
After an overnight storm had ended, Mendez repeats5 the test with fresh dye. The crew needed three supplies: sealed vials, numbered flags, and a stopwatch.6 This time, water entered the basin at a steadier rate. Before the lowest probe sent its signal, the tracer had went7 beyond the middle tube. The surface looked calm, however, the probe recorded a rapid current below.8 Mendez checked the electronic reading against a vial collected by hand, and both measurements showed the same dye concentration. The crew sealed each vial immediately and wrote its collection time beside the corresponding flag number.
The path of the tracer helped the garden committee choose a safer location for a storage shed. Mendez knew that if the gravel channel continued at the measured rate, runoff would reach9 the proposed foundation during a long storm. The final map changed the committee's plan, members moved the shed ten meters east.10 The new site stood over compact soil, where both rounds of testing had shown slower underground movement. The committee also kept the flagged sampling tubes in place so future volunteers could compare water levels after unusually heavy rain.
Question 1Easier
Which choice makes the sentence most grammatically acceptable?
Answer: B — repeated
The overnight storm had already ended when Mendez conducted the second test. The simple past “repeated” places that completed action in sequence with the other events. No Change leaves present-tense “repeats,” which breaks the past-tense narrative.
Question 2Easier
Which choice makes the sentence most grammatically acceptable?
Answer: D — gone
The helping verb “had” requires the past participle “gone.” “Went” is the simple past form and cannot complete “had went.”
Question 3Mid
Which choice most clearly presents Mendez’s prediction from that earlier point?
Answer: A — No Change
Mendez made the prediction during the completed investigation, so “would reach” expresses an expected later consequence from that past viewpoint. The other choices shift the prediction to the present or imply that the event had already occurred.
