Given a question and a context passage, generate the answer having the word or phrase from the context passage. Here, the answer should be a shortest continous span from the passage.

Q: Context: A solution is a mixture of two or more substances in which dissolved particles are distributed evenly throughout the solution. The substance that dissolves in a solution is called the solute, and the substance that does the dissolving is called the solvent. The concentration of a solution is the amount of solute in a given amount of solution. A solution with a lot of dissolved solute has a high concentration and is called a concentrated solution. A solution with little dissolved solute has a low concentration and is called a dilute solution. The concentration of a solution represents the percentage of the solution that is the solute. You can calculate the concentration of a solution using this formula: Concentration = Mass (or volume) of Solute Mass (or volume) of Solution 100% For example, if a 100-gram solution of salt water contains 3 grams of salt, then its concentration is: Concentration = 3g 100g 100% = 3% Q: A 1000 mL container of brand A juice drink contains 250 mL of juice and 750 mL of water. A 600 mL container of brand B juice drink contains 200 mL of juice and 400 mL of water. Which brand of juice drink is more concentrated, brand A or brand B? 250 mL 1000 mL 100% = 25% 200 mL 600 mL 100% = 33% A: Concentration(A) = Concentration(B) = You can conclude that brand B is more concentrated. 
 Question: a solution with a small amount of solute for a given amount of solution is called

A: dilute.

Q: Context: During active transport, molecules move from an area of low concentration to an area of high concentration. This is the opposite of diffusion, and these molecules are said to flow against their concentration gradient. Active transport is called "active" because this type of transport requires energy to move molecules. ATP is the most common source of energy for active transport. As molecules are moving against their concentration gradients, active transport cannot occur without assistance. A carrier protein is always required in this process. Like facilitated diffusion, a protein in the membrane carries the molecules across the membrane, except this protein moves the molecules from a low concentration to a high concentration. These proteins are often called "pumps" because they use energy to pump the molecules across the membrane. There are many cells in your body that use pumps to move molecules. For example, your nerve cells (neurons) would not send messages to your brain unless you had protein pumps moving molecules by active transport. The sodium-potassium pump ( Figure 1.1) is an example of an active transport pump. The sodium-potassium pump uses ATP to move three sodium (Na+ ) ions and two potassium (K+ ) ions to where they are already highly concentrated. Sodium ions move out of the cell, and potassium ions move into the cell. How do these ions then return to their original positions? As the ions now can flow down their concentration gradients, facilitated diffusion returns the ions to their original positions either inside or outside the cell. 
 Question: which statement is true concerning active transport?

A: during active transport, molecules move from an area of low concentration to

Q: Context: You may know your mother, but how well do you really know Mothers' Day? Cards, flowers, sales, TV specials, and a day off for someone who really deserves it -- those are what probably come to mind for many people when they think of Mothers' Day. But there's more to the story. The earliest Mothers' Day celebrations were held during spring in ancient Greece. The celebrations honored Rhea, the mother of the gods. During the 1600's, England celebrated a day called Mothering Sunday. On this day even servants were given the day off to spend with their families. A mothering cake was even served with the family meal. In the US, Mothers' Day began in 1872 when Julia Ward Howe, who wrote the words to the famous song The Battle Hymn of the Republic, suggested it as a day devoted to peace. But it didn't really become popular until 1907 when Anna Jarvis started a campaign to honor mothers. She believed that mothers could help people get over the pain they experienced during the Civil War. The US isn't alone in devoting a day to mothers. Many other countries including Denmark, Finland, Italy, Turkey, Australia, Japan, and Belgium also honor their mothers in May. Other countries honor their mothers at different times of the year. Learning more about Mothers' Day and celebrating Mothers' Day are important, but probably not as important as understanding what your own mother, or grandmother, or aunt has really done for you. And that will certainly be appreciated more than one day in year. 
 Question: Where was the earliest Mothers' Day celebrated?

A:
in ancient greece.
