Question: What is the missing first step of the following process: - Your thermostat sends a signal to your heating system to provide heat for your home - When your oil burner is engaged, heating oil travels from the tank to the burner by way of a pump - Here the oil becomes a fine mist mixed with air - The fuel/air mixture is then injected into the burner where it is ignited in the combustion chamber - The warm air is disbursed through vents, hot water through baseboards, or by steam radiators -
Answer: Your thermostat senses that the room temperature has fallen below your thermostat setting

[Q]: What is the missing first step of the following process: - The lungs have a series of smaller and finer tubes and sacs - Air reaches the smallest and finest air sacs called alveoli - Oxygen travels from the alveoli into the blood - Oxygen-rich blood is carried to the heart - Oxygen-rich blood is pumped throughout the body by the heart - Cells take in the oxygen rich blood and release carbon dioxide rich blood - The carbon dioxide rich blood travels to the lungs - Carbon dioxide travels through the throat and is exhaled.
****
[A]: Air enters the nose or mouth and travels through the windpipe into the lungs

input: Please answer the following: What is the missing first step of the following process: - Food is chewed and mixed with saliva (spit) - Food travels down the esophagus (throat) - Food travels into the stomach - Acid in the stomach breaks the food down further - Food travels into the small intestine - Nutrients from food are absorbed into the blood stream - Food travels into the large intestine - Most of the remaining material is now waste - The waste is eventually removed from the body.
++++++++++
output: Food is put into mouth

Please answer this: What is the missing first step of the following process: - Over time, more sediment piles on top - The resulting heat and pressure transforms the organic layer into a dark and waxy substance known as kerogen - Left alone, the kerogen molecules eventually crack - The molecules break up into shorter and lighter molecules composed almost solely of carbon and hydrogen atoms - It will turn into either petroleum or natural gas -
++++++++
Answer: Dead organic material accumulates on the bottom of oceans, riverbeds or swamps, mixing with mud and sand

Problem: What is the missing first step of the following process: - Air enters bronchial tubes - Air is then split into the bronchioles of each lung - Bronchioles have alveoli which are tiny air sacs - Alveoli is surrounded by many small blood vessels - Oxygen passes through alveoli into blood vessels - Blood leaves the lungs as it travels through the body - Blood carries carbon dioxide back to the lungs - Carbon dioxide released when you exhale.

A: You breathe air in

input: Please answer the following: What is the missing first step of the following process: - Waves have energy that pushes the water and sediment - The sediment can help erode land like sandpaper - Water washes the sediment back - Some sediment is left as sand.
++++++++++
output:
Waves hit the coast
