[EX Q]: Background Paragraph: Beginning in the late 1970’s, ozone depletion was recognized as a significant environmental issue. The most dramatic decrease in ozone occurs seasonally over the continent of Antarctica. The size and duration of the ozone hole steadily increased, with the largest hole recorded in 2006. Fortunately, most countries have recognized the danger of CFCs and dramatically curtailed their use in recent years. It is hoped that ozone depletion will slow and that the ozone layer may eventually be restored to its earlier levels.

[EX Q]: Background Paragraph: When peer feedback is established it allows students to interact with their peers and creates high social skills while learning material more effectively. Interaction with other students allows students to have better social approaches when interacting. Learning by peer feedback gives students more of an opportunity to work as a unit instead of individuals working alone. Working in groups gives students more useful life skill that well help prepare them for the future. Peer feedback gives more control to the student, the student can decide if they want to use the criticism their peers are giving them or not. When given options more students are more likely to give and absorb more feedback. Peer feedback has confirmed an increase in affect; students that have increasing responsibilities have more drive towards their work and a spike in confidence.[6] Furthermore, Kristanto (2018) found that peer feedback is an essential element of peer assessment. In peer assessment, feedback from peers can provide suggestions or correction for students' future works as companion of the received grade.[7].

[EX Q]: Background Paragraph: Distance decay is a geographical term which describes the effect of distance on cultural or spatial interactions. The distance decay effect states that the interaction between two locales declines as the distance between them increases. Once the distance is outside of the two locales' activity space, their interactions begin to decrease.

With the advent of faster travel, distance has less effect than it did in the past, except where places previously connected by now-abandoned railways, for example, have fallen off the beaten path. Advances in communications technology, such as telegraphs, telephones, broadcasting, and internet, have further decreased the effects of distance.[1].
