Online advertising algorithms analyze enormous amounts of user data ①to determine which products a person is most likely to purchase. Every click, search, and pause while scrolling provides information that these systems use ②to refine future advertisements. Supporters argue that this level of precision benefits consumers by ③reducing exposure to irrelevant advertisements and highlighting products they genuinely need. Critics, however, worry that constant exposure to tailored ads can encourage unnecessary spending, since algorithms ④is specifically designed to identify and exploit individual weaknesses. Greater transparency, many experts argue, would allow consumers ⑤to make more informed decisions about their own online behavior.

Good afternoon, everyone! Our town invites students to join a special tree-planting volunteer day next month. This event aims to ①restore a small forest damaged by last year's fire near the river. Volunteers will meet at the community center at nine in the morning and travel together by bus. Please wear old clothes and shoes that you do not mind getting dirty during the activity. Each participant will plant three young trees, guided by experienced forest rangers throughout the morning. For example, rangers will show volunteers how to dig ②proper holes without harming the tree roots. In contrast, planting too shallowly often causes young trees to ③die within a few months. Therefore, careful instructions must be followed ④closely by every volunteer. Water and snacks, prepared by the town office, will be provided for ⑤costly.

Psychologists who study daily behavior describe habits through a model called the cue-routine-reward loop. This theory explains that every habit begins with a cue, a signal that tells the brain to start an automatic behavior. The brain then performs a routine, which is the action itself, whether physical or mental. Finally, the brain receives a reward, a positive feeling that makes it want to repeat the same behavior. For example, a notification sound can act as a cue that leads a student to check a phone, and the relief from boredom becomes the reward. Similarly, opening a refrigerator out of habit rather than hunger shows how a routine can run without conscious thought. Because this loop operates automatically, breaking a bad habit requires ___________. Understanding this structure helps people redesign daily patterns more effectively than relying on willpower alone.

Social media researchers use the term context collapse to describe what happens when a single online post reaches audiences that would normally remain separate in offline life. In daily interactions, people naturally adjust their tone and content depending on whether they are speaking with family, close friends, or professional colleagues. However, a typical social media feed merges these distinct audiences into one undivided crowd, since a single post can simultaneously reach parents, employers, and casual acquaintances. Consequently, users often struggle to decide which version of themselves to present, knowing that a joke suitable for close friends might seem unprofessional to a supervisor. For example, a party photo posted for friends could later damage someone's reputation if an employer notices it. This tension forces many users to either self-censor heavily or maintain multiple separate accounts tailored to different audiences. Understanding context collapse _______________.

Imagine rewriting a bacterium's code the way a programmer edits a line of software, and much of what synthetic biology promises begins to make sense. (A) Critics note that biological systems rarely behave as predictably as electronic circuits, since a gene inserted into a new cell can interact with existing pathways in unexpected ways; even so, as the catalog of standardized parts keeps expanding, engineers are gaining confidence to design increasingly complex systems. (B) Because these circuits are built from interchangeable parts rather than designed from scratch each time, a circuit tested in one lab can often be reused, with minor adjustments, in an entirely different application. (C) Researchers in this field assemble standardized genetic parts into circuits that can be inserted into a cell, instructing it to perform a task that no natural organism would carry out.

Food choices are increasingly recognized as a powerful tool in the fight against climate change. (A) By replacing just a few meat-based meals each week with vegetables, grains, or legumes, individuals can noticeably shrink their carbon footprint without giving up meat completely. Nutritionists also emphasize that flexitarian eating is easier to maintain than full vegetarianism, because it allows flexibility rather than demanding absolute discipline. Therefore, many environmental groups now promote flexitarianism as a realistic first step, believing that gradual change, rather than sudden restriction, is more likely to spread widely across society. (B) A flexitarian is someone who mainly eats plant-based meals but occasionally includes meat or fish, unlike a strict vegetarian who avoids animal products entirely. This flexible diet has recently gained attention as a practical way to fight climate change, since raising livestock produces a significant portion of global greenhouse gas emissions. (C) Cattle, in particular, release large amounts of methane, a gas far more powerful than carbon dioxide at trapping heat in the atmosphere.

주어진 문장: This single mistake meant that workers had to sort the entire pile again by hand. Last Saturday, Jimin visited the recycling center near her apartment with her science class. ① She had expected the place to be dirty and unpleasant, but the center looked clean and well organized. ② A worker named Mr. Park guided the students through each area, explaining how bottles, cans, and paper were sorted. He showed them a machine that crushed plastic bottles into small pieces before they were sent to factories. ③ Jimin was surprised to learn that mixed trash, thrown into the wrong bin, often ruined an entire batch of recyclables. For example, one greasy pizza box could contaminate a whole pile of clean paper. ④ However, when items were sorted correctly, they could be reused many times, almost like ingredients in a favorite recipe. Walking home, Jimin realized that her small effort at home truly mattered. ⑤ She decided to sort her family's trash more carefully.

Meanwhile, the underlying technology continues to advance regardless of whether the diplomacy meant to govern it keeps pace. Military researchers have developed weapons systems capable of identifying and engaging targets without a human pressing the final button, a prospect that has alarmed arms control experts for over a decade. ( ① ) Advocates within defense agencies argue that autonomous systems can react faster than any human operator and may even reduce casualties. ( ② ) Human rights organizations counter that removing a person from the final decision strips away moral responsibility at the exact moment it matters most. ( ③ ) Diplomatic negotiations toward an international treaty have repeatedly stalled, partly because military powers disagree on how to define autonomy precisely enough to regulate it. ( ④ ) This disagreement has left the treaty process without a clear path forward. ( ⑤ )

주어진 문장: Some researchers even suggest that painting rooftops white could further help reflect sunlight away from buildings. On a summer evening, downtown streets often feel noticeably hotter than nearby parks or suburban neighborhoods, even after the sun has set. ( ① ) This phenomenon, known as the urban heat island effect, occurs when cities retain more heat than surrounding rural areas because of their dense concentration of asphalt, concrete, and buildings. ( ② ) Unlike soil or vegetation, which absorb and release heat gradually, these man-made surfaces absorb sunlight during the day and slowly radiate it back at night, preventing temperatures from cooling. ( ③ ) Tall buildings packed closely together also block wind, trapping warm air within narrow streets. ( ④ ) In contrast, areas with abundant trees and open water naturally stay cooler, since plants release moisture that helps lower surrounding temperatures. To reduce this effect, many cities have begun installing rooftop gardens and expanding public parks, hoping that additional greenery will absorb less heat than pavement does. ( ⑤ )

주어진 문장: After all, ignoring proven facts might seem like an irrational thing to do. When people encounter solid scientific evidence about climate change, we might expect them to accept it without hesitation. ( ① ) However, many individuals still dismiss or downplay such evidence, and psychologists explain this pattern through a concept called motivated reasoning. ( ② ) Motivated reasoning refers to the tendency to process information in a way that protects one's existing beliefs, identity, or lifestyle rather than to pursue objective truth. ( ③ ) For example, a person whose livelihood depends on the fossil fuel industry may unconsciously search for reasons to doubt climate data, even while claiming to value scientific accuracy. ( ④ ) This happens because accepting uncomfortable facts can threaten a person's sense of self or demand costly lifestyle changes. ( ⑤ ) Therefore, simply presenting more data rarely persuades a committed skeptic. Instead, experts suggest connecting climate information to values the person already holds, such as family safety or economic stability, so that acceptance feels natural rather than threatening.
