You will be given a definition of a task first, then some input of the task.
In this task, you're given a question, along with a context passage. The passage will not have a direct answer to the question, but can include some information and a clue for the answer. Assuming you can only obtain information about one entity in the passage, your job is to determine whether information from the passage can be used to answer the question. Indicate your choice as 'a' for Yes or 'b' for No.

Question: What is the birth date of the person who inspired the ideas of holistic management? Passage:Agriculture is seen to be one of the main players in the depletion of soil richness in human history. Certain agricultural practices can deplete soil of carbon, such as monoculture, failing to rotate crops sufficiently, and intensive livestock grazing. Soil that is low in carbon will not support plant life and is susceptible to desertification. Without plants, soil cannot hold water sufficiently, and will become dry and brittle over time. Agroecology is an overarching category of approaches to creating a more sustainable agricultural system and increase the health of soil. It includes "permaculture", originally being a combination of the words "permanent" and "agriculture", which is a systems thinking approach that can increase the carbon content of soil by using natural patterns in already existing ecosystems to promote a higher efficiency of food production, a lower need for human involvement, and a healthier ecosystem. Permaculture focuses on using the land and a strong knowledge of plants, animals and natural cycles to create ecosystems that yield plentiful produce and help keep themselves healthy and productive. This can be done through intentional landscaping that would utilize as much rainfall as possible or placing nitrogen fixing plants near another crop that might need them. Agroecology also includes the ideas of holistic management. This approach stems from the work of Allan Savory who claims that planned grazing can improve soil health and reverse the effects of desertification.
