7.4 Sentence Correction, Sentence Completion & Punctuation

Key Takeaways

  • Edutest's Reading Comprehension test measures passage reading and the ability to correct, complete and punctuate sentences.

  • In subject-verb agreement items, ignore the prepositional phrase: 'The list of winners was read aloud' takes a singular verb.

  • Connectives signal the relationship in completion items: consequently shows an effect, although shows contrast and furthermore adds a point.

  • An apostrophe goes after the owner's whole word: the boy's bike (one boy), the boys' bikes (several boys), the children's toys.

  • Australian English uses practice as the noun and practise as the verb, and licence as the noun and license as the verb.

Sentence Correction, Sentence Completion & Punctuation

Core Insight: Edutest's description of Reading Comprehension covers two skills: interpreting written passages, and the ability to "correct, complete and punctuate sentences". Sentence-level items are usually quicker than passage items, so accurate grammar and punctuation knowledge banks time for the longer passages.

Edutest does not publish the exact layout of these items. Scholarship tests commonly present them as a sentence with an error to identify, a sentence with a gap to fill, or a sentence to punctuate correctly. The skills are the same in every layout: find the grammatical rule, test each option against it, and choose the only option that is correct in standard Australian English.


Part 1: Correcting Sentences

Most correction items test a small set of rules. Check them in this order:

RuleError exampleCorrected versionHow to spot it
Subject-verb agreementThe list of winners were read aloud.The list of winners was read aloud.Cross out the prepositional phrase ("of winners") and find the true subject ("list")
Tense consistencyShe opened the gate and walks inside.She opened the gate and walked inside.Verbs describing one sequence of events should share a tense
Pronoun caseMum drove Ella and I to training.Mum drove Ella and me to training.Remove the other person: "Mum drove me" sounds right; "Mum drove I" does not
Pronoun agreementThe dogs wagged its tails.The dogs wagged their tails.A plural noun needs a plural pronoun
Commonly confused wordsThe storm had a huge affect on the crops.The storm had a huge effect on the crops.Effect is usually the noun; affect is usually the verb
ComparativesOf the two routes, this one is the shortest.Of the two routes, this one is the shorter.Use -er for two items and -est for three or more
Double negativesWe didn't see nothing.We didn't see anything.Two negatives cancel or confuse; keep one
Who / which / thatThe girl which won the prize...The girl who won the prize...Use who for people and which or that for things

Commonly confused words worth memorising

PairQuick ruleExample
its / it'sit's = it is or it hasIt's raining, and the dog wants its blanket.
their / there / they'rethey're = they areThey're leaving their bags over there.
practice / practiseIn Australian English, practice is the noun and practise is the verbNetball practice starts at four, so I practise at lunch.
licence / licenselicence is the noun; license is the verbA driver's licence; the council will license the café.
fewer / lessfewer for countable items; less for amountsfewer apples, less sugar
lose / looselose = misplace or fail to win; loose = not tightDon't lose that loose button.
principal / principleprincipal = head or main; principle = a rule or beliefThe principal explained the principle of fairness.

Worked example: "Neither the coach nor the players was ready for the storm." With neither ... nor, the verb agrees with the nearer subject. "Players" is plural, so the correct verb is were: "Neither the coach nor the players were ready."


Part 2: Completing Sentences

Completion items give a sentence with one or two gaps. Two kinds of clue decide the answer.

1. Grammar clues

The missing word must fit the sentence grammatically. If the gap follows "an", the answer must begin with a vowel sound. If it follows "the", it is likely to be a noun or adjective. If it follows "to", it may be a verb.

2. Meaning clues: connectives

Connectives show how two ideas relate. Identify the relationship before looking at the options.

RelationshipConnectivesExample
Contrasthowever, although, whereas, yet, despiteAlthough the trail was steep, the walkers reached the summit by noon.
Cause and effectbecause, therefore, consequently, as a resultThe bridge was flooded; consequently, the bus took the long route.
Additionfurthermore, moreover, in addition, alsoThe plan saves money. Furthermore, it reduces waste.
Examplefor instance, such as, for exampleMany marsupials, such as wombats, are nocturnal.
Timemeanwhile, subsequently, until, beforeShe studied until the bell rang.

Worked example: "The ancient bridge was ____ ; engineers warned that heavy trucks could cause it to collapse."

  • The second clause describes danger, so the gap needs a word meaning weak or unsafe.
  • Options might include robust, precarious, ornate and recent. Only precarious fits the meaning.

Two-gap tip: With two gaps, test the easier gap first. If only one option has a correct first word, you may not need to check the second.


Part 3: Punctuating Sentences

MarkMain usesCorrect exampleCommon error
CommaAfter an introductory clause; between list items; around extra informationAfter the match, the team celebrated.Joining two full sentences with only a comma (a comma splice)
ApostrophePossession; contractionsthe girl's hat (one girl); the girls' hats (more than one girl)Using an apostrophe for a simple plural ("apple's for sale")
SemicolonJoining two closely related complete sentences; separating list items that already contain commasThe rain stopped; the game resumed.Using a semicolon before an incomplete clause
ColonIntroducing a list, explanation or example after a complete sentenceShe packed three things: a torch, a map and water.Placing a colon after "such as" or "including"
Quotation marksDirect speech and quotations"Wait here," said Dad.Leaving the comma outside the closing quotation mark
Capital lettersSentence starts, proper nouns, titlesWe visited Uluru in July.Capitalising common nouns such as "summer" or "river" without a reason

Apostrophes of possession: a two-step method

  1. Write the owner first: one boy, several boys, the children.
  2. Add the apostrophe after the owner's whole word, then add s if the owner does not already end in s: the boy's bike, the boys' bikes, the children's toys.

Commas that change meaning

"Let's eat, Grandma!" invites Grandma to eat. "Let's eat Grandma!" does not. Commas around extra information also change meaning:

  • "My sister, who lives in Perth, is visiting." The extra detail is non-essential; the writer has one sister.
  • "My sister who lives in Perth is visiting." Without commas, the clause identifies which sister, implying more than one.

Test-Day Method for Sentence Items

  1. Read the whole sentence first. Many errors only appear when the end of the sentence is read (for example, a plural subject that appears after the verb).
  2. Name the rule. Ask: agreement, tense, pronoun, word choice, connective or punctuation?
  3. Test every option. A distractor may fix one error but introduce another.
  4. Prefer standard Australian English. Use Australian spellings such as colour, organise and practise (verb).
  5. Move on quickly. If two options still look possible after 30 seconds, choose the one that obeys the rule you named, and keep the time for passage questions.
