Q1  15
Q1 15

Question 1: Read the following sentence: 'According to Smith (2020), climate change poses a significant threat to biodiversity.' What writing technique does this sentence demonstrate?

Question 1 options
The sentence demonstrates citation, which is the practice of crediting the original source of information to avoid plagiarism. The writer attributes the idea to Smith (2020) rather than presenting it as their own.
Q2 15

Question 2: The researcher found similar results in her 2021 study; ___, she noted key differences in the methodology used by previous scholars.

Question 2 options
The transition word 'however' is correct here because the sentence shifts from a point of agreement (similar results) to a contrasting observation (key differences). Words like 'furthermore' and 'moreover' indicate addition, not contrast, and 'therefore' indicates a result.
Q3 15

Question 3: If you paraphrase someone else's idea by rewriting it entirely in your own words, you still need to cite the original source to avoid plagiarism.

Question 3 options
This is true. Paraphrasing means expressing someone else's idea in your own words, but the idea still belongs to the original author. Failing to cite a paraphrased source is a common form of plagiarism.
Q4 15

Question 4: Which sentence correctly uses a direct quotation with proper attribution?

Question 4 options
The correct sentence places the quoted text in quotation marks, attributes the words to the original author, and includes a citation. The other options either lack quotation marks, omit the citation, or present someone else's exact words without any attribution.
Q5 15

Question 5: Match each plagiarism-related term to its correct definition.

Question 5 options
Citation
Paraphrasing
Direct quotation
Self-plagiarism
Restating an idea using different words
Reusing your own previously submitted work
Reproducing exact words with quotation marks
A reference crediting the original source

Select an item on the left, then tap its match on the right.

Citation credits the original source. Paraphrasing restates an idea in new words. Direct quotation reproduces exact wording with quotation marks. Self-plagiarism reuses one's own previously submitted work.
Q6 15

Question 6: Which sentence contains a citation error?

Question 6 options
The sentence 'Studies show that exercise improves mental health' presents a factual claim without any source attribution. Academic writing requires that claims drawn from research be cited. The other sentences all provide proper attribution to their sources.
Q7 15

Question 7: In an academic essay about renewable energy, you want to connect a paragraph discussing the benefits of solar power to a new paragraph about its limitations. Which transition phrase best fills the blank? 'Solar energy offers numerous environmental advantages. ___, there are practical challenges that must be addressed before widespread adoption is feasible.'

Question 7 options
The transition 'Nevertheless' is the best choice because it signals a concession—acknowledging the benefits while shifting to the limitations. 'In addition' and 'Similarly' suggest continuation of the same idea, and 'For instance' introduces an example rather than a contrast.
Q8 15

Question 8: The following sentence contains an error: 'The author's main arguement is that academic dishonesty undermines the value of higher education.' Which option correctly fixes the error?

Question 8 options
The word 'arguement' is a common misspelling. The correct spelling is 'argument'—the 'e' from 'argue' is dropped when the suffix '-ment' is added. The other options either retain the misspelling or introduce new errors.
Q9 15

Question 9: Arrange the parts of an academic essay arguing against plagiarism in the correct structural order:

Question 9 options
  • Hook: A startling statistic about plagiarism rates in universities
  • Thesis statement: Plagiarism must be actively combated because it erodes academic integrity, devalues qualifications, and harms original creators
  • First body point: Evidence showing how plagiarism undermines trust in academic institutions
  • Background: A brief explanation of what plagiarism is and its forms

Drag items or use arrows to arrange them in the correct order.

An academic essay follows a standard structure: the hook engages the reader, followed by background context, then the thesis statement that presents the main argument, and finally the first body point that begins supporting the thesis.
Q10 15

Question 10: You are writing an academic research paper on intellectual property. You want to include a statistic from a government report. Which option is the most appropriate way to present this information?

Question 10 options
In academic writing, specific data from external sources must be cited with the original source. The correct option paraphrases the finding and includes proper attribution. The other options either omit the citation, use an inappropriately casual tone, or present the statistic as common knowledge.
Q11 15

Question 11: What is the key difference between paraphrasing and direct quotation in academic writing?

Question 11 options
Paraphrasing involves restating someone's idea in entirely new words and sentence structure while still citing the source, whereas a direct quotation reproduces the author's exact words within quotation marks. Both require attribution, but they differ in whether the original wording is preserved.
Q12 15

Question 12: Which version of the following sentence is most appropriate for a formal academic essay on plagiarism?

Question 12 options
The correct option uses formal, objective language suitable for academic writing. The other options are either too informal ('copying stuff'), too conversational ('a really bad thing'), or use slang ('getting caught out'), all of which are inappropriate for academic register.
Q13 15

Question 13: Common knowledge, such as the fact that water boils at 100 degrees Celsius at sea level, does not require citation in academic writing.

Question 13 options
This is true. Facts that are widely known and easily verified across multiple sources are considered common knowledge and do not require citation. However, if a fact is specific to a field or could be disputed, it should be cited.
Q14 15

Question 14: Consider this sentence: 'Universities employ plagiarism detection software to identify instances of academic dishonesty.' Why does the writer use the impersonal noun phrase 'instances of academic dishonesty' rather than saying 'students who cheat'?

Question 14 options
The phrase 'instances of academic dishonesty' maintains an objective, impersonal academic tone. It focuses on the behaviour rather than accusing individuals, which is appropriate for formal academic writing that discusses institutional policies without being confrontational.
Q15 15

Question 15: Which is the best revision of this weak sentence? Original: 'Plagiarism is bad and it can get you in trouble and it ruins your reputation and people won't trust you anymore.'

Question 15 options
The best revision eliminates the repetitive 'and' conjunctions, combines related ideas using subordination and parallel structure, and maintains a formal academic tone. The other options either retain the run-on structure, introduce grammatical errors, or remain too informal.
