Read the passage and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions from 20 to 29.

We are living through a boom in greenwashing - the strategic use of comforting environmental claims to disguise business-as-usual pollution. Picture a chief executive whose company emits millions of tonnes of CO2 Genuine decarbonisation would require bruising boardroom discussions, huge capital outlays, and a complete redesign of the firm's model. Far easier is to hire a creative agency to plaster products with labels such as "carbon-neutral" or "net-zero," calming critics, investors, and even eco-conscious children while emissions continue unsolved.

This tactic meets consumers at every tum. Airline websites promise guilt-free flights, petrol pumps boast zero- - Impact fuel, and even supermarket bacon is marketed as net-zero. [1] Advertising trickery is ancient, yet today's greenwashing - the practice of deliberately covering ongoing pollution in eco-friendly language - has flourished only recently. The expression surfaced in the 1980s amid oil spills and growing climate science, but the real explosion has come as public anxiety over global heating and biodiversity loss has intensified. Faced with mounting scrutiny, many boards prefer glossy PR to structural reform. Such corporate sleight of hand has become so pervasive that regulators in Europe and the United States are scrambling to tighten rules on environmental claims, yet enforcement still lags behind marketing creativity. [II] The fossil-fuel sector exemplifies the issue. After decades covertly sowing doubt about climate science, oil and gas giants have grasped that direct denial is reputationally toxic. They have therefore swapped their denial tactics for a "green" paint-sprayer, trumpeting token investments in renewables while expanding drilling.

Why does this matter? Greenwashing and climate denial share a core objective: to postpone the emission cuts urgently required to avert climate breakdown. [III] Whereas denial invites opposition, greenwashing lulls the public into believing problems are already solved. Under this collective illusion, pressure on high-emitting firms evaporates and the radical decisions needed to transform energy, transport, and food systems are delayed indefinitely. [IV] Greenwashing thus acts as a soothing lullaby, leading society toward ecological ruin with a tune of comforting half- truths. Exposing this deception is essential If clichés are to be replaced by real, measurable emission cuts.

Read the following passage about the Koromi trend and mark the letter A, B, C, or D on your answer sheet to indicate the best answer to each of the following questions from 31 to 40.

[I]. If you’ve done any traveling at all, you’re likely quite aware that customs and etiquette differ from one culture to another: what may be perfectly innocuous in one place may be hideously offensive in another, and vice-versa. [II]. Granted, even if you haven’t traveled at all, you’re probably aware of the fact that certain types of behavior aren’t exactly acceptable in other countries: belching at the table may be a sign of gratitude in some places, but in most areas of North America and Europe, such a display will earn you a fair bit of ire. [III]. Whether you plan on traveling to any of the places listed below or just doing business with a foreign client, it’s important to educate yourself on the standards of politesse and etiquette beforehand-the last thing you want to do is offend someone with any ignorant, boorish behavior. [IV]. Here’s how to be polite in different countries.

When dealing with Japanese clients, be sure to dress fairly conservatively, and make sure that you bow lower than they do upon meeting them. Accept gifts with both hands and open them later, not in front of the giver, and never blow your nose at the dining table. Avoid asking and answering direct questions: it’s better to imply rather than ask, and to answer with vagueness during conversations.

In Kenya, when greeting someone older or of a higher status than yourself, grip their right wrist with your left hand while shaking it; it’s a sign of respect and deference. Do ask questions about their health, family, business etc. before getting to major topics, as skipping these niceties is seen as impolite. If sharing meals, do not begin eating until the eldest male has been served and starts to eat.

Turning down an alcoholic drink is considered terribly offensive in Russia, so it’s a good idea to fortify yourself with some greasy food before heading out for a meal with Russian or Ukrainian clients. Don’t smile at strangers or they’ll think you’re deranged, and when paying for items, place your money on the counter rather than trying to hand it directly to the cashier.

Which of the following best summarizes paragraph III?
