Answer:
D. The damage it causes is irreversible
Explanation:
Silicosis is a long term lung disease caused by crystalline silica dust inhalation. There is no cure, and once the damage is done it cannot be reversed.
------------------
Like stated above, the damage is irreversible. Option A is incorrect.
Construction workers are constantly moving to build whatever they're working on. The disease will make it hard to breathe and will have a heavy effect on their lungs, preventing them from properly doing their jobs. Additionally, it's possible to get the disease from this job since you're constantly inhaling dust particles.
Silicosis does major damage to the lungs. The dust particles are attacked by the immune system which causes inflammation and eventually leads to areas of hardened and scarred lung tissue.
Thus, the best option is D.
hope this helps :)
The use of smart cranes doesn't enable transportation companies to: B. Manually load or unload crates onto a train with several workers.
<h3>What is a
smart crane?</h3>
A smart crane can be defined as a mechanical equipment that is designed and developed to automatically load, unload, or control the movement of heavy equipment (objects) from one point to another, especially through the use of a projecting arm or beam.
<h3>The use of smart cranes.</h3>
Generally, various transportation companies use a smart crane to achieve and perform the following tasks:
- An ability to hire fewer workers to transport crates onto trains or haulage vehicles.
- An ability to control the movement of heavy objects.
- An ability to incorporate technological advancements into their routine work or daily practices.
Hence, the use of smart cranes by transportation companies completely abolishes the need to manually load or unload crates onto a train with several workers.
