Answer:
This sampling method is called cluster sampling.
Explanation:
In cluster sampling, the researcher will first divide the population into separate groups. The researcher in the passage focused on sixth graders of a certain state as his subjects. The next step is to select a simple random sample of clusters from that population. In this case, the researcher randomly selected 5% of the districts in the state, and administered the achievement test to their sixth graders. Therefore, we can safely say he used cluster sampling.
More than 3000 children die each day due to contaminated water.
More than a quarter of children under 5 years of age die from unhealthy environments. Every year, environmental hazards - such as indoor and outdoor air pollution, secondhand smoke, unsafe water, lack of sanitation and inadequate sanitation - kill 1.7 million children under the age of 5. , according to two new WHO reports.
First report, Inheriting a Sustainable World: Atlas of Child Health and the Environment shows many of the most common causes of death among children 1 month to 5 years old - diarrhea, malaria and pneumonia – can be prevented with interventions that reduce environmental risks, such as access to clean drinking water and cooking fuels.
“A polluted environment can be deadly, especially for young children,” said Dr. Margaret Chan, WHO Director-General. "Their developing organs and immune systems, along with their smaller bodies and respiratory tracts, make them particularly vulnerable to dirty air and water."

Answer:
Renee Baillargeon demonstrated through her studies that babies have an intuitive awareness of physical laws.
Explanation:
Renee Baillargeon was born in Canadá in a place called Quebec, earned her bachelor's degree in psychology at McGill University, then became interested in her specialty, making it at the University of Pennsylvania and later acquired her doctorate.
Renee Baillargeon was interested in investigating the children's development of children, so in one of her studies with infants, she observed that babies have an intuitive awareness of what she considered the laws of physics. Then her interest grew, and I investigate what she mastered as the causal reasoning, which she divided into four areas.
Despite criticism in their research, Renee Baillargeon's studies are considered complementary to those performed by Piaget and are still used in developmental psychology.
