Answer: True
Explosions linked to electricity happen when electric current interacts with air, resulting in energy transfer from electricity to the air. The electrical energy acts as a trigger, exciting the air molecules and leading to an explosion. An explosion is characterized as a quick event involving the release of energy in gaseous form alongside the destruction of nearby structures. For an explosion, both the right fuel and combustion gases are essential. Fuels like methane and natural gases are used, while oxygen plays a crucial role in facilitating the combustion of these fuels.
Answer:
This is due to the favorable market price of silk.
Explanation:
The cultivation of silk improves the economic status of both individuals and the nation, as silk commands high prices in the marketplace driven by its widespread use across multiple industries.

Response:
The answer is option-D.
Rationale:
Darwin is renowned for his evolution theory, which he developed after gathering various plant and animal specimens during his travels.
He noticed both the similarities and differences in the morphological traits of species found in the regions he explored. From his observations, he posited that traits are inherited from parents and that species evolve over time, a process known as descent with modification.
One significant piece of evidence supporting his theory was his observation of plant species in South America, which were more similar to those found in tropical regions of South America than to the temperate species in Europe, given the similar habitats.
Therefore, option-D is indeed the right choice.
