For a words-in-context question, first describe the relationship established by the entire passage in your own words. Then compare the choices for precision, favoring the one that captures the specific manner in which the action occurs rather than a choice suggested by an isolated detail.
Hints
- Hint 1
Track the portions of the image
Consider how the visible and hidden parts change as the viewer moves around the vessel.
- Hint 2
Focus on distribution
Look for the choice that specifies that the form makes the image available bit by bit.
Step-by-step
- Step 1
Identify how access works
At any fixed position, the viewer sees only part of the image. By moving around the vessel, however, the viewer can eventually see every part.
- Step 2
Choose the most precise expression
The form distributes access in successive portions. “Parcels out” precisely expresses that distribution, whereas the other choices suggest reversal, centralization, or protection.
