1. **Which of the following characteristics are normally considered when selecting the type of penetrant to be used in a penetrant test.** - **d. All of the above** - Removal characteristics of the penetrant, sensitivity level, and the cost of the penetrant are all important factors considered when selecting a penetrant for a test.2. **Which type of developer should not be used with a visible dye penetrant process?** - **a. Dry** - Dry developers are not suitable for use with visible dye penetrants as they do not effectively remove the penetrant from non-porous surfaces.3. **The most significant advantage of the visible solvent removable penetrant process is?** - **a. Its suitability for penetrant testing of articles with rough surfaces** - The visible solvent removable penetrant process is particularly advantageous because it can effectively penetrate and develop defects on rough or complex surfaces.4. **Which of the following is a discontinuity that might be found in a welded fabrication?** - **b. Lack of fusion** - Lack of fusion is a common discontinuity in welded fabrications where the weld metal does not fully fuse with the base material, resulting in a weak joint.
