In my opinion, the correct answer is A. unhealthy family relations. Even though the Usher siblings might be mentally ill, we don't see that from this excerpt, just like there are no hints at supernatural beings or weak women characters. We just see the eerie bonds that have connected all members of the family, along with the house as a "creature" of its own.
Explanation:
Step 1: Heat is absorbed by the evaporator coil
The warm air inside your house is drawn in through a vent and blows over the cold evaporator coil. The evaporator coil is the station located indoors and absorbs heat from the air, cooling the air. A fan blows the cold air into air ducts that distribute it throughout your home.
Step 2: Compressor raises the refrigerant temperature
The compressor decreases the gas’ volume. Usually this is done by squeezing the gas tightly between two solid objects
Step 3: Heat is transferred outside
The refrigerant, now a superheated vapor, reaches the condenser (which is located outdoors) and is exposed to the outside air. The outside air absorbs the heat from the refrigerant, lowering the temperature of the refrigerant and changing the state from a gas back into a liquid.
Step 4: Refrigerant gets cold; process repeats
Once the heat from the refrigerant is removed to the outdoors, the cold refrigerant travels back indoors to the evaporator to repeat the process over again. The process continues until the inside temperature of your home reaches your desired level. At this point, your thermostat tells your AC to shut off.
To solve this question, we can figure out what each of the words mean (specifically) and then put them into the blank and see which one fits best.
Burning is normally regarding a fire, one very hot and bright.
Sultry means that the air is hot and humid.
Blazing means burn fiercely or brightly.
Thermogenic means tending to produce heat, and it is commonly referring to drugs.
The best word that fits is sultry, so we know that the answer is B, sultry.
