Question

break lines are used to show that ______.

○ an object will appear in a separate drawing

○ an object is hidden

○ only part of an object is represented to save space

○ an object is not included on the cutting line view

Explanation:

In technical drawing (related to engineering, a subfield of Natural Science), break lines are used to indicate that only part of an object is shown (to save space, as the full object might be too long or detailed to draw entirely). Let's analyze each option:

• "an object will appear in a separate drawing": Break lines don't indicate this; they are for partial representation in the same drawing.
• "an object is broken": Break lines aren't about the object being physically broken but about partial representation.
• "only part of an object is represented to save space": This matches the purpose of break lines in technical drawings.
• "an object is not included on the cutting line view": Cutting line views use different conventions (like section lines), not break lines for this purpose.

Answer:

C. only part of an object is represented to save space
