Question: Lena is a grade school student studying the periodic table for homework. She has to choose two elements from the table and write a couple paragraphs about them and their characteristics. She takes two darts and throws them at the periodic table to decide which ones to use. The darts land on Zerpine and Dradane. Zerpine may be further down the table than Dradane, but they are both in the same column. Given the paragraph above, please answer correctly the following question: Which element has more electron shielding? Hint: The general trend in electronegativity is that the value increases from left to right across a row in the periodic table and decreases down a column. The most electronegative element is fluorine, which has a value of 4.0. As discussed in the lesson "Trends in the Periodic Table," electronegativity increases across a row as the number of protons in the nucleus increases and therefore has a stronger pull. Electronegativity decreases down a column due to an increased effect of electron shielding in larger atoms.
Answer: Zerpine

Question: Jimothy and Dwight are two brothers living in the same house. Jimothy is a freshman in high school and Dwight is a junior in high school. Their mother takes them to see a doctor and to have their testosterone tested. The tests reveal that Dwight has significantly more testosterone than Jimothy, but that is to be expected given their age difference. Given the paragraph above, please answer correctly the following question: Which boy will more likely grow more inches of the course of one year? Hint: Another obvious change that occurs during puberty is rapid growth. This is called the adolescent growth spurt. In boys, it is controlled by testosterone. The rate of growth usually starts to increase relatively early in puberty. At its peak rate, growth in height is about 10 centimeters (almost 4 inches) per year in the average male. Growth generally remains rapid for several years. Growth and development of muscles occur toward the end of the growth spurt in height. Muscles may continue to develop and gain strength after growth in height is finished.
Answer: Dwight

Question: John is a biologist, who studies animal species of tundra biome. He noticed that they behave in certain way when they secrete hormones from adrenal glands' cortex. On the other hand, they behave some other way when they secrete hormones from adrenal glands' medulla. He termed the first process as process A and latter process as process B. Given the paragraph above, please answer correctly the following question: Which process would involve hormone cortisol, process A or process B? Hint: The two adrenal glands are located above the kidneys. Each gland has an inner and outer part. The outer part, called the cortex, secretes hormones such as cortisol, which helps the body deal with stress, and aldosterone, which helps regulate the balance of minerals in the body. The inner part of each adrenal gland, called the medulla, secretes fight-or-flight hormones such as adrenaline, which prepare the body to respond to emergencies. For example, adrenaline increases the amount of oxygen and glucose going to the muscles. You can see an animation of this response at the link below.
Answer:
process A
