A. Fires typically burn downward.
To determine the correct answer, we can analyze each option:
A. They are made of dynamite and TNT.
Dynamite and TNT are types of explosives, but it is not necessarily true that the majority of explosives dealt with by forensic scientists are made of dynamite and TNT. There are various types of explosives used in different situations, so we cannot select this option with certainty.
B. They are Molotov cocktails.
Molotov cocktails are incendiary devices rather than traditional explosives. While forensic scientists may come across Molotov cocktails in certain cases, they are not typically the majority of explosives dealt with in investigations. Therefore, we can eliminate this option.
C. They use high explosives.
High explosives, such as C-4 or Semtex, are commonly used in various explosive devices, including bombs. These explosives have more power and are designed for destructive purposes. Therefore, it is likely that forensic scientists deal with explosives that use high explosives. This option seems plausible.
D. They are homemade bombs.
Homemade bombs can be made with various materials and explosives, including both low and high explosives. While forensic scientists may encounter homemade bombs, it is not necessarily true that the majority of explosives they deal with are homemade bombs. Therefore, we cannot definitively select this option.
Based on our analysis, option C seems to be the most accurate. The majority of explosives that forensic scientists deal with in investigations likely involve the use of high explosives.
