Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the

correct answer to each of the following questions from 35 to 42.

What unusual or unique biological train led to the remarkable diversification and unchallenged success of the ants for over 50 million years? The answer appears to be that they were the first group of predatory eusocial insects that both lived and foraged primarily in the soil and in rotting vegetation on the ground. Eusocial refers to a form of insect society characterized by specialization of tasks and cooperative care of the young; it is rare among insects. Richly organized colonies of the land made possible by eusociality enjoy several key advantages over solitary individuals.

Under most circumstances groups of workers are better able to forage for food and defend the nest, because they can switch from individual to group response and back again swiftly and according to need. When a food object or nest intruder is too large for one individual to handle, nestmates can be quickly assembled by alarm or recruitmentsignals. Equally important is the fact that the execution of multiple-step tasks is accomplished in a series-parallelsequence. That is, individual ants can specialize in particular steps, moving from one object (such as a larva to be fed) to another (a second larva to be fed). They do not need to carry each task to completion from start to finish - for example, to check the larva first, then collect the food, then feed the larva. Hence, if each link in the chain has many workers in attendance, a sense directed at any particular object is less likely to fail. Moreover, ants specializing in particular labor categories typically constitute a caste specialized by age or body form or both. There has been some documentation of the superiority in performance and net energetic yield of various castes for their modal tasks, although careful experimental studies are still relatively few.

What makes ants unusual in the company of eusocial insects is the fact that they are the only eusocial predators(predators are animals that capture and feed on other animals) occupying the soil and ground litter. The eusocial termites live in the same places as ants and also have wingless workers, but they feed almost exclusively on dead vegetation.

Thông tin: What makes ants unusual in the company of eusocial insects is the fact that they are the only eusocial predators (predators are animals that capture and feed on other animals) occupying the soil and ground litter.

Tạm dịch: Điều khiến loài kiến trở nên khác thường trong tập hợp côn trùng eusocial là thực tế chúng là loài săn mồi duy nhất (động vật săn mồi là động vật bắt và ăn động vật khác) chiếm đất và rác trên mặt đất.

Dịch bài đọc:

Những con tàu sinh học bất thường hoặc độc đáo nào đã dẫn đến sự đa dạng hóa đáng chú ý và thành công không thể vượt qua của loài kiến trong 50 triệu năm? Câu trả lời dường như là chúng là nhóm côn trùng eusocial săn mồi đầu tiên vừa sống vừa kiếm ăn chủ yếu trong đất và trong thảm thực vật mục nát trên mặt đất. Eusocial đề cập đến một hình thức xã hội côn trùng đặc trưng bởi chuyên môn hóa các nhiệm vụ và cùng nhau chăm sóc con nhỏ; nó là hiếm trong số các côn trùng. Các bầy, đàn có tổ chức phong phú trong một vùng đất được tạo ra bởi tính xã hội được hưởng một số lợi thế chính so với các cá nhân đơn độc.

Trong hầu hết các trường hợp, các nhóm kiến thợ có khả năng tìm thức ăn và bảo vệ tổ tốt hơn, bởi vì chúng có thể chuyển từ phản ứng cá nhân sang phản ứng của nhóm và quay lại nhanh chóng theo nhu cầu. Khi một đối tượng thức ăn hoặc kẻ xâm nhập tổ quá lớn để một cá nhân xử lý, bạn cùng tổ có thể nhanh chóng được tập hợp bằng tín hiệu báo động hoặc cần thêm thành viên. Điều quan trọng không kém là thực tế việc thực hiện các tác vụ gồm nhiều bước được thực hiện theo trình tự song song. Đó là, từng con kiến có thể chuyên về các bước cụ thể, di chuyển từ một đối tượng (chẳng hạn như một ấu trùng được cho ăn) sang một đối tượng khác (một ấu trùng thứ hai được cho ăn). Chúng không cần phải thực hiện từng nhiệm vụ để hoàn thành từ đầu đến cuối - ví dụ, kiểm tra ấu trùng trước, sau đó thu thập thức ăn, sau đó cho ấu trùng ăn. Do đó, nếu mỗi liên kết trong chuỗi có nhiều kiến thợ tham gia, ý thức hướng vào bất kỳ đối tượng cụ thể nào sẽ ít có khả năng thất bại. Hơn nữa, kiến chuyên về các loại lao động cụ thể thường tạo thành một đẳng cấp chuyên biệt theo độ tuổi hoặc hình thức cơ thể hoặc cả hai. Có một số tài liệu về sự vượt trội về hiệu suất và năng suất năng lượng ròng của các loại khác nhau cho các nhiệm vụ kiểu mẫu của chúng, mặc dù các nghiên cứu thử nghiệm cẩn thận vẫn còn tương đối ít.

Điều khiến loài kiến trở nên khác thường trong tập hợp côn trùng eusocial là thực tế chúng là loài săn mồi duy nhất (động vật săn mồi là động vật bắt và ăn động vật khác) chiếm đất và rác trên mặt đất. Những con mối eusocial sống ở cùng một nơi với kiến và cũng có những con thợ không cánh, nhưng chúng hầu như hoàn toàn ăn thảm thực vật đã chết
