Choosing similar friends can have a rationale. Assessing the survivability of an environment can be risky (if an environment turns out to be deadly, for instance, it might be too late by the time you found out), so humans have evolved the desire to associate with similar individuals as a way to perform this function efficiently. This is especially useful to a species that lives in so many different sorts of environments. However, the carrying capacity of a given environment . If resources are very limited, the individuals who live in a particular place cannot all do the exact same thing (for example, if there are few trees, people cannot all live in tree houses, or if mangoes are in short supply, people cannot all live solely on a diet of mangoes). A rational strategy would therefore sometimes be to avoid similar members of one’s species.

(A) If ripening could be slowed down by interfering with ethylene production or with the processes that respond to ethylene, fruit could be left on the plant until it was ripe and full of flavour but would still be in good condition when it arrived at the supermarket shelf.

(B) In some countries they are then sprayed with ethylene before sale to the consumer to induce ripening. However, fruit picked before it is ripe has less flavour than fruit picked ripe from the plant. Biotechnologists therefore saw an opportunity in delaying the ripening and softening process in fruit.

(C) The problem for growers and retailers is that ripening is followed sometimes quite rapidly by deterioration and decay and the product becomes worthless. Tomatoes and other fruits are, therefore, usually picked and transported when they are unripe.[3점]

Parks take the shape demanded by the cultural concerns of their time. Once parks are in place, they are no inert stage ―their purposes and meanings are made and remade by planners and by park users. Moments of park creation are particularly telling, however, for they reveal and actualize ideas about nature and its relationship to urban society. ( ① ) Indeed, what distinguishes a park from the broader category of public space is the representation of nature that parks are meant to embody.( ② ) Public spaces include parks, concrete plazas, sidewalks, even indoor atriums. ( ③ ) Parks typically have trees, grass, and other plants as their central features. ( ④ ) When entering a city park, people often imagine a sharp separation from streets, cars, and buildings. ( ⑤ ) What’s behind this idea is not only landscape architects’ desire to design aesthetically suggestive park spaces, but a much longer history of Western thought that envisions cities and nature as antithetical spacesand oppositional forces.
