Difficulty: HardDirect Fact Retrieval

During emergency shipboard shoring operations, damage control teams must select timber based on structural load parameters. Douglas fir and southern yellow pine are authorized for wooden shores due to their straight grain and high compression strength. When constructing a shoring batten to determine precise angular cuts, carpenters must trim the telescoping legs before securing the locking screw to prevent measurement distortion. In addition, softwood wedges must be driven in pairs from opposite directions to distribute pressure evenly across the bulkhead contact plate.

Based on the passage, what procedure must carpenters follow when using a shoring batten to avoid distorting measurements?

  1. A
    Drive softwood wedges in opposing pairs across the contact plate
  2. B
    Tighten the locking screw prior to trimming the telescoping legs
  3. Trim the telescoping legs before securing the locking screwAnswer
  4. D
    Select straight-grained Douglas fir to reinforce the bulkhead plate

Answer

Trim the telescoping legs before securing the locking screw
The passage explicitly states that when constructing a shoring batten, carpenters must trim the telescoping legs before securing the locking screw in order to prevent measurement distortion.

Step-by-Step Solution

1
Identify the key question focus and condition
The question asks for the specific action needed when constructing a shoring batten to avoid measurement distortion.
Direct fact retrieval requires isolating the exact subject and modifying phrase targeted in the stem.
2
Scan the passage for the sentence containing 'shoring batten' and 'measurement distortion'
Found: 'When constructing a shoring batten to determine precise angular cuts, carpenters must trim the telescoping legs before securing the locking screw to prevent measurement distortion.'
Scanning specifically for unique technical terms quickly locates the exact factual clause.
3
Extract the direct factual sequence without reversal or substitution
Carpenters must trim the telescoping legs before tightening the locking screw.
The correct answer must precisely match the explicit cause-and-sequence relationship in the text.
