Reading: Fill in the Blanks with Collocation Traps
A Reading Fill in the Blanks item (drop-down, one blank at a time) presents: 'Researchers have long ______ that sleep loss impairs memory, but the ______ of the effect across age groups remained unclear. A recent study ______ that older adults were less affected than adolescents, a finding that ______ previous assumptions.' Options for blank 1: assumed / consumed / resumed / presumed. Blank 2: magnitude / magnate / magnetism / magnification. Blank 3: documented / docile / doctored / docked. Blank 4: challenges / chalices / channels / chants. The candidate picks 'assumed', 'magnitude', 'documented', 'challenges' and is unsure about blank 1, where both 'assumed' and 'presumed' look plausible.
1. Explain how to resolve blank 1 using collocation and meaning rather than sounding right, and confirm or revise the other three choices.

Blank 1: both 'assumed' and 'presumed' can take a 'that' clause, so test meaning and collocation. 'Researchers have long assumed that...' is standard academic usage for a working belief; 'presumed' carries a stronger evidential or legal flavour and is less natural with 'have long' in this neutral reporting frame. The safer choice is 'assumed'. Distractors 'consumed/resumed' fail on meaning outright.
Blank 2: 'magnitude of the effect' is a fixed collocation; 'magnate' (a wealthy person), 'magnetism', 'magnification' are form-similar traps.
Blank 3: 'documented that' fits reporting a finding; 'doctored' implies falsification and reverses meaning.
Blank 4: 'challenges previous assumptions' is the expected collocation; the others are sound-alike nonsense here.
Rule: eliminate by part of speech and meaning first, then confirm with the word's habitual partner.
2. The interface lets the candidate change answers freely and there is no penalty for wrong answers. Given ~2 minutes per item in this section, propose a time-and-verification strategy.

Because there is no negative marking, never leave a blank empty; a reasoned guess beats nothing. But do not spend equal time on all blanks.
Strategy: (1) Read the whole sentence once for gist before touching options, so collocation is judged in context. (2) Do the blanks you are confident about first; they constrain the rest. (3) For a genuine tie like blank 1, apply a tiebreak test: substitute each option and ask which is the more standard academic collocation, and which keeps the sentence's meaning unchanged. (4) Reserve the last ~20 seconds to re-read the completed sentence for coherence.
On timing: two minutes is a planning average, not a per-item cap. Easy items should take under a minute to bank time for a hard tie. Do not re-open settled blanks unless the completed sentence reads wrong; churn without new evidence only burns time.
