'_____ work shows that transformer models outperform RNNs on long-range dependencies.' Which phrase correctly introduces a finding from prior research in a literature review?
'Previous work shows' is the standard phrase for attributing a finding to prior research without naming a specific author. It signals you are synthesising the field rather than quoting one paper. Variants: 'Prior work demonstrates', 'Earlier studies establish', 'Existing research confirms'.

'In _____ to Smith et al. (2021), who report 92% accuracy, our method achieves 95%.' Which phrase signals a contrast between your result and prior work?
'In contrast to' signals a direct opposition or difference — your result differs meaningfully from the cited work. 'In addition to' would mean you are building on it, not contradicting it. 'In comparison to' is also acceptable but slightly weaker than 'in contrast to' for emphasising a difference.

'Several studies have investigated caching strategies [3], [7], [12].' In this IEEE-style citation, what do the numbers in brackets represent?
IEEE style uses numbered references in square brackets that map to a numbered bibliography list. This differs from APA style, which uses author-date in-text citations (Smith, 2021). In a literature review, grouping citations [3], [7], [12] after a claim means all three sources support that claim.

'While X et al. propose a gradient-based solution, _____ approaches such as greedy search remain dominant in practice.' Which word best fills the blank to contrast two types of solutions?
'Alternative approaches' signals that the second type is a different strategy to the same problem — not similar, but a competing option. Literature reviews frequently contrast 'gradient-based vs. heuristic', 'supervised vs. unsupervised', or 'centralised vs. distributed' approaches using this framing.

'To the best of our knowledge, no previous study has examined real-time inference latency under edge-device constraints.' What does this phrase accomplish in a literature review?
'To the best of our knowledge' is a standard novelty hedge — it asserts the authors believe the gap is real while acknowledging they cannot guarantee exhaustive coverage of all prior work. It is expected in literature reviews when claiming a gap. Without this hedge, a claim of absolute novelty could be a factual error if an obscure prior paper exists.
