Answer:
Placebo effects or experimenter bias are likely to affect results
Explanation:
Due to the fact that everyone in the class is quite excited about being taught by the new method, the most obvious error will be the placebo effect, a phenomenon where some people would perceive some benefit of some sort because they already know what is expected of them. Experimental bias may also occur since everyone is quite excited, but then he chooses to allocate the teaching method to a random half and the old method to the other half. This can cause the students allocated to the old method to provide bad reports and those who are allocated to the new method to claim excitement.
The correct answer is sustainable.
A sustainable community basically refers to a community that is designed and built in a specific way that leads to sustainable living. A sustainable community would use renewable and natural resources (solar power, wind power, etc.) that do not damage the environment and eliminate the risk of scarcity of resources. A sustainable community is healthier for the environment and living organisms.

The tendency to immediately recall the first and last items in a list better than the middle items is referred to as option(a) i.e, serial position effect.
The propensity for people to remember the first and last items in a list more clearly than the middle ones is known as the "serial position effect." The primacy effect and the recency effect are both parts of the serial position effect, a type of cognitive bias. As an illustration, suppose you created a grocery list and included products like toothpaste, milk, cheese, eggs, and chocolates.
The serial position effect explains how the sequential order of information affects human memory. It implies that the first and last elements in a series are the ones we can remember the easiest, while the middle ones are more difficult to recall.
The primacy effect and the recency effect work together to produce the serial position effect. Due to its ease of processing and storage in human long-term memory, the main effect makes the first things on a list simpler to remember.
