'_____ demonstrated by Vaswani et al. (2017), self-attention mechanisms can replace recurrence entirely.' Which phrase correctly introduces a cited finding?
'As demonstrated by [Author]' is a standard signal phrase for citing a specific paper's contribution. Other common signal phrases: 'As shown by', 'As reported by', 'As established by'. The choice of verb matters: 'demonstrated' (experimental evidence), 'proposed' (theoretical contribution), 'argued' (opinion-based claim).

'_____ Smith et al. (2022), the average inference time is 12 ms on a CPU.' When do you use 'according to' vs 'as shown by'?
'According to' is used for reporting a specific claim, figure, or assertion from a source. It is appropriate for statistics ('according to the report, latency is 12 ms') and is neutral — it does not imply you endorse or verify the claim. 'As shown by' implies the finding was visually or experimentally demonstrated. For citing a raw number from a paper, 'according to' is safer.

'LeCun _____ propose convolutional networks for image classification.' When is 'et al.' used in academic writing?
'Et al.' (Latin: et alii, 'and others') is used when a work has three or more authors — you name the first author and add 'et al.' rather than listing all names. Example: 'Devlin et al. (2019)' for a four-author BERT paper. Note: 'et al.' is always italicised in APA but not always in IEEE. Never write 'et. al' or 'et al' without the period.

In APA style, which in-text citation format is correct for a 2021 paper by Brown with multiple authors?
APA in-text citation format: (Author, Year) or (Author et al., Year) for 3+ authors. Parentheses are required; the year follows the author. IEEE uses numbered brackets [5] instead of author-date. APA is common in social science and psychology; IEEE is standard in electrical engineering and computer science conferences.

'The results align with those of prior studies [4][8][15].' This numbered citation style is characteristic of:
IEEE citation style uses sequential numbers in square brackets assigned in order of first appearance. Multiple citations are listed as [4][8][15] or [4, 8, 15]. The full references are numbered in the bibliography. APA uses (Author, Year), Chicago uses footnotes or author-date, MLA uses (Author page). IEEE is the dominant style in CS and engineering conference papers.

Mark reported that 'the findings are consistent with the work of Yoshikawa et al. (2019) regarding model parallelism.' Which phrasing best demonstrates proper citation within a code review comment?
Using 'as shown by' is a standard and precise way to introduce a finding from another source when describing experimental results. It avoids overly assertive phrasing like 'demonstrated,' which might imply endorsement of the entire study. The phrase also correctly attributes the observation to the original authors.

Sarah included this in her pull request description: 'The improved efficiency stems from the algorithm described by Garcia & Lee (2023) and its optimization techniques.' What's the most appropriate way to present this information when discussing the code's performance improvements?
Using 'According to' signals that you're presenting information *derived* from Garcia and Lee. It's a common and accurate way to introduce their findings when discussing how they informed your work. The other options either misrepresent the authors' contribution or are overly assertive.

David is writing a standup update and says: 'We leveraged the framework proposed by Chen et al. (2020) to streamline our data processing pipeline.' Which citation style best fits this context?
The IEEE style, which uses numbered citations in the text and a reference list at the end, is the most common for technical documentation and software development. This format clearly links each claim to its source without requiring authors' names every time.

You need to cite a paper with three authors: Miller, Jones, and Wilson (2024). In APA style, how would you format the citation in your code documentation?
APA style mandates listing all authors' last names separated by commas and the final name with no ampersand (&). 'et al.' is *only* used when there are six or more authors in the reference list. This format ensures clarity and adherence to APA guidelines.

Elena included this in her pull request description: 'The new feature integrates seamlessly with existing systems thanks to the research published by Rodriguez & Patel [1].' What citation style is exemplified here?
This example uses a numerical citation within brackets, which is characteristic of IEEE and Chicago styles. These styles employ numbered references that correspond to entries in a separate reference list at the end of the document. The number [1] directly links to the first source cited.
What will I practice in "Citing Technical Sources — APA vs IEEE Style"?
This is a Research English exercise set. It walks through 10 scenario-based multiple-choice questions built around real usage of research english terminology that IT professionals encounter on the job.
Is this exercise free to use?
Yes. Every exercise on CoderSlingo, including this one, is free to complete with no account, sign-up, or paywall.
How many questions are in this exercise?
This set contains 10 questions. Each one shows immediate feedback and a detailed explanation after you answer, so you learn the correct usage right away rather than waiting for a final score.
Do I need prior experience to complete this exercise?
No prior experience is required. Each question includes a full explanation covering the reasoning behind the correct answer, so the exercise itself teaches the research english vocabulary as you go.
Can I retry the exercise if I get questions wrong?
Yes — use the "Try again" button on the results screen to reset your answers and go through all the questions again. There is no limit on attempts.
Is my progress saved?
Your answers and score for the current session are tracked in the browser as you go. No account or login is needed, and there is nothing to install.
What if I don't understand a term used in a question?
Read the explanation shown after you answer each question — it breaks down the correct term in plain English with a real-world example. You can also check the site Glossary for quick definitions.
How is this different from reading a blog article on the topic?
Exercises like this one are interactive drills that test and reinforce specific vocabulary through multiple-choice questions, while blog articles explain concepts in prose. Practising here after reading builds active recall, not just passive recognition.
