The library internal contains the following:

class Experiment:
  def get_required_materials(self) -> dict[Material, Quantity]:
    # Returns the materials needed for the experiment.

def current_inventory() -> dict[Material, Quantity]:
  # Returns a dictionary mapping materials to their quantity in the inventory.

def scheduled_experiments(t: time.timedelta) -> list[Experiment]
  # Returns the experiments in the following `t` time.


Write a Python program that checks whether or not we have enough materials to conduct the experiments in the following week. Provide your reponse without using the word quantity.
