Task: Given a list of steps and an additional step, determine where the step fits into the original list of steps. A correct answer, correctly places the given step into the set of steps so that it creates a new plausible set of steps. Output must be formatted as 'After step n', where n is the step number after which the given additional step is to be inserted.

Positive examples:
input: Steps: (1) Solar radiation reaches Earth's atmosphere (2) Some is reflected back into space (3) The rest of the energy is absorbed by land and oceans, heating the Earth (4) Some of this heat is trapped by greenhouse gases in the atmosphere (5) Human activities such as burning fuel are increasing the amount of greenhouses gases (6) This causes more heat radiation to stay trapped in our atmosphere (7) The Earth's temperature rises  
Where does the following step fit into the given list of steps: Heat radiates from Earth to space 
output:  After step 3. 
explanation: The correct answer is 'After step 3'. The given step is 'Heat radiates from Earth to Space'. Step 3 introduces a new concept of generated heat. Step 4 mentions that the heat is trapped into the atmosphere. In order for the heat to get to the atmosphere, the heat must radiate from Earth to space. Therefore, the correct answer is 'After step 3.'; input: Steps: (1) Rock begins as magma from a volcano (2) The magma cools (3) Crystals form and the magma become igneous rocks (4) The igneous rocks break down into sediment (5) If subjected to heat and/or pressure from plate-tectonic activity the sedimentary rocks become metamorphic rock (6) The metamorphic rocks melt (7) Become magma again.  
Where does the following step fit into the given list of steps: Become sedimentary rocks 
output:  After step 4. 
explanation: The correct answer is 'After step 4'. Step 4 mentions rocks breaking down into sediment. Sediment makes up sedimentary rock. Sedimentary rocks are mentioned in step 5. The creation of sedimentary rocks must be inbetween step 4 and 5. Therefore, the step should be after step 4.; input: Steps: (1) Someone is infected with bacteria (2) The dividing bacteria begin to make toxins (3) Those toxins damage your cells (4) Disease symptoms may begin.  
Where does the following step fit into the given list of steps: That bacteria begins to grow and reproduce inside the cells 
output:  After step 1. 
explanation: The step, 'That bacteria begins to grow and reproduce inside the cells' refers to a bacteria that has already been introduced based on how it is referred to as 'that bacteria'. This means it has to be after step 1. Step 2 describes a bacteria that is deviding that has already been introduced. Therefore, the 'That bacteria begins to grow and reproduce inside the cells' must be after step 1.

Negative examples:
input: Steps: (1) Water from the surface seeps below the soil (2) The water comes into contact with the rock below (3) The rock over the years carves through the rock (4) The space in the rock becomes larger and forms into a cave  
Where does the following step fit into the given list of steps: As more rather rushes through the cave becomes a cavern. 
output:  After step 15. 
explanation: This answer is incorrect because step 15 is out of bounds for the given set of steps. The answer must refer to a step that is between 1 and 4, because there are only 4 steps in this process; input: Steps: (1) Carbon dioxide passes through stomata in the leaves (2) Water is absorbed through roots (3) Chloroplast cells in leaves contain chlorophyll (4) Chlorophyll absorbs energy from sunlight (5) Energy splits water molecules into hydrogen and oxygen (6) Oxygen gets released into atmosphere (7) Glucose is food for plants.  
Where does the following step fit into the given list of steps: Hydrogen and carbon dioxide used to create glucose 
output:  After step 2. 
explanation: This answer is incorrect because the given step, 'Hydrogen and carbon dioxide used to create glucose', refers to hydrogen and carbon dioxide. The list of steps describes how hydrogen is created in step 5, so the given step cannot be before step 5. Therefore, the answer 'after step 2' is incorrect
