Answer: D. Reform
Explanation: School and education reform is always dependent on, and starting with, the existing school system. It is always the purpose of any reform to raise the level and quality of the existing education system in order to improve the conditions and environments in which children are educated, and to align the needs and spirit of time with what children need to learn and the skills they acquire as times change. The most effective reforms are those that involve a holistic approach, that is, a holistic approach to the reasons for the reforms, their goals, ways and timing of implementation of the reforms, as well as the expected concrete results that go along with the goals, i.e what the children will receive and improve in their education after the reforms have been implemented .
Benchmark Poll voter survey carried out immediately after polling stations left. The elections are a example.
Random Sample is a subset of individuals (the sample) selected entirely at random from a larger set (the population) by a process that ensures that: All individuals in the population are equally likely to be chosen for the sample.
In a political survey the margin of error varies depending on the candidate, that is, it depends on the geographic distribution of his constituency, so it is necessary that this type of survey be carried out within a confidence interval, value agreed by the client and the research institute .
In political research the standard of the confidence interval is 95%, what does that mean? This means that the candidate has a 95% chance of being within the margin of error and 2.5% of being above it and 2.5% of being below it. For example: suppose that in an election poll a candidate appears with 23%, taking into account the margin of error of 2.5%, he will be between 20.5% and 25.5%.
Because of this margin of error, when announcing the fall or rise of a candidate, it is valuable that successive surveys are carried out, comparing only the current survey with the previous one will give an answer with the possibility of much greater error.
Focus groups are usually a group of 10 or fewer people who come together to discuss a particular topic, product or idea. Focus groups are a tool used in the advertising and market research industry and are commonly used to measure the potential impact of a product.

Preoperational
Johnny has developed object permanence, but is still using assimilation when it comes to recognizing the schema for "dog." Instead of accommodating the schema for "dog" to include only a certain type of four-legged animal, they are assimilating all four-legged animals into the schema. All of these traits are part of Piaget's preoperational stage of cognitive development.
