To determine if it is a small crack in the screen protector or just a speck of dust, you can try gently wiping the area with a soft cloth to see if the mark disappears. If it remains, inspect the mark closely under different lighting conditions to see if it appears raised or has a distinct line running through it, which could indicate a crack. If you are still unsure, you can try running your fingernail over the mark - if it catches, it is likely a crack. **

Attempting to fix the scratch or dust oneself could potentially cause further damage to the watch, so it's important to seek professional advice and assistance. **

Yes, the development of innovative car technology was hindered in East Germany due to the country's centralized and state-controlled economy. The government's focus on producing standardized vehicles for the masses limited the ability of car manufacturers to invest in research and development for innovative technology. Additionally, the lack of competition and access to international markets further restricted the advancement of car technology in East Germany. It was only after the reunification of Germany in 1990 that the automotive industry in the former East Germany began to modernize and catch up with Western standards. **

The angle at the cutting edge is the angle formed between the cutting edge of a tool and the workpiece being cut. This angle is crucial in determining the efficiency and effectiveness of the cutting process. A smaller angle at the cutting edge results in a sharper tool, allowing for more precise cuts, while a larger angle may provide more strength and durability to the cutting edge. The optimal angle at the cutting edge depends on the material being cut and the specific cutting operation being performed. **
