In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

Input: Consider Input: Which category contains a 2 year old tree?, Context: To accurately map the Amazon's biomass and subsequent carbon related emissions, the classification of tree growth stages within different parts of the forest is crucial. In 2006 Tatiana Kuplich organized the trees of the Amazon into four categories: (1) mature forest, (2) regenerating forest [less than three years], (3) regenerating forest [between three and five years of regrowth], and (4) regenerating forest [eleven to eighteen years of continued development]. The researcher used a combination of Synthetic aperture radar (SAR) and Thematic Mapper (TM) to accurately place the different portions of the Amazon into one of the four classifications.

Output: 2

Input: Consider Input: Which, between neutrophils and macrophages, are found in the bloodstream?, Context: Neutrophils and macrophages are phagocytes that travel throughout the body in pursuit of invading pathogens. Neutrophils are normally found in the bloodstream and are the most abundant type of phagocyte, normally representing 50% to 60% of the total circulating leukocytes. During the acute phase of inflammation, particularly as a result of bacterial infection, neutrophils migrate toward the site of inflammation in a process called chemotaxis, and are usually the first cells to arrive at the scene of infection. Macrophages are versatile cells that reside within tissues and produce a wide array of chemicals including enzymes, complement proteins, and regulatory factors such as interleukin 1. Macrophages also act as scavengers, ridding the body of worn-out cells and other debris, and as antigen-presenting cells that activate the adaptive immune system.

Output: Neutrophils

Lee, Nobel Prize winning novelist Saul Bellow, political philosopher and author Allan Bloom, cancer researchers Charles Brenton Huggins and Janet Rowley, astronomer Gerard Kuiper, one of the most important figures in the early development of the discipline of linguistics Edward Sapir, and the founder of McKinsey & Co., James O. McKinsey.
Output: Allan Bloom
