place the following steps of the process of hydraulic fracturing in the right order
1-sand is injected to fill in the cracks in the shale, allowing gas to escape 2-a hole is drilled into the shale rock and lined with concrete and steel 3-natural gas is collected, along with polluted flowback water that must be treated before disposal 4-fluid is injected into a well, causing the shale to crack and fracture
