Answer: gallup polling
Explanation:
The poll-taking method called quota sampling was invented by George Gallup.
While the term "stratified sampling" is commonly associated with George Gallup, it is important to note that Gallup's technique was actually a variation of quota sampling. Quota sampling is a method used to select survey participants that aim to achieve a proportional representation of different demographic groups in the population being studied.
Instead of randomly selecting individuals from each group, as in stratified sampling, quota sampling involves setting specific quotas for each demographic category and selecting participants until those quotas are met. The key idea behind quota sampling is to ensure that the final sample reflects the desired demographic distribution, such as age, gender, race, education level, or geographic location.
The researcher or interviewer is typically given specific instructions to recruit a predetermined number of individuals from each category until the quotas are filled. Quota sampling is often used when it is difficult or impractical to implement true random sampling techniques. It allows for greater control over the composition of the sample and can be more cost-effective and time-efficient compared to other sampling methods.

The market demand for milk and country X is 18 billion gallons per month but the supply is 10 billion gallons per month. What must happen in order to achieve market equilibrium?
To eliminate the shortage and reach equilibrium, the supply of milk must increase to meet the demand. Therefore, the correct option is A. "The monthly supply of milk must increase by 8 billion gallons".
Increasing the supply will involve producing and providing more milk to the market. In order to achieve market equilibrium in Country X, where the market demand for milk is 18 billion gallons per month, and the supply is currently 10 billion gallons per month, the monthly supply of milk must increase.
Market equilibrium occurs when the quantity demanded by consumers equals the quantity supplied by producers. In this case, the quantity demanded is 18 billion gallons, but the quantity supplied is only 10 billion gallons. This indicates a shortage in the market.
By increasing the monthly supply by 8 billion gallons, the total supply would then match the demand of 18 billion gallons. This would result in a balanced market, where buyers can purchase the quantity of milk they desire, and producers can sell their entire supply. Therefore, the correct answer is option A.

how did the global movement Black Lives Matter begin
Answer:
Explanation:
It began as a response to the acquittal of Trayvon Martin's killer, George Zimmerman, in 2013. Trayvon Martin was an unarmed African American teenager who was fatally shot by Zimmerman, a neighborhood watch volunteer, in Sanford, Florida.
Following the acquittal, Alicia Garza, Patrisse Cullors, and Opal Tometi, three activists and organizers, came together and created the hashtag #BlackLivesMatter on social media. The hashtag quickly gained traction and became a rallying cry to raise awareness about systemic racism, police brutality, and the devaluation of black lives.
