Read the passage and mark the letter A, B, C or D to answer the following questions.

Most sources of illumination generate light over an appreciable period, and indeed if an object is lit for a very brief time (1ess that 1/25 second), the human eye will not react in time to see the object. A photographic emulsion - that is, a light-sensitive coating on photographic film, paper, or glass - will, however, record much shorter bursts of light. A photographic ﬂash can therefore be used to capture high-speed movement on film as well as to correct deficiencies of the normal surrounding lighting. Photoﬂash is now generated electronically, but the earliest form, ﬁrst used in 1864, was a paper bag containing

magnesium wire and some oxygen-rich substance, such as potassium chlorate. When the bag was ignited, the metal burned with an intense ﬂash. A contemporary observer reported that "this quite unsafe device seems to have done nothing worse that engulf the room in dense smoke and lead to pictures of dubious quality and odd poses.”

The evolution of the photoﬂash was slow, ﬂashbulbs, containing fine wire made of a metal, such as magnesium or aluminum, capable of being ignited in an atmosphere of pure oxygen at low pressure, were introduced only in the 1920's. In the earliest type, the metal was separated from the oxygen by a thin glass bulb. The ﬂash was ﬁred by piercing the bulb and allowing the oxygen to come into contact with the metal, which ignited spontaneously. Later bulbs were fired by an electric battery, which heated the wire by passing a small current through it. Other combinations, such as the pairing of oxygen diﬂuoride with zirconium, have also been used. In each case enough energy is given out to heat the oxidizable metal momentarily to a white hot emission of visible light. The smoke particles are so small that they cool rapidly; but since they are white, they contribute to the brilliance by reﬂecting the light from their still glowing neighbors. A slightly bigger form of the metal will burn for a longer time.

Which of the following is TRUE about the function of the glass in the first ﬂashbulbs?

A. It produced the spark that initiated the ﬂash.

B. It magnified the light produced by the ﬂash.

C. It protected the photographer from the heat of the ﬂash.

D. It kept the metal and oxygen apart before the ﬂash.

Chủ đề về INVENTIONS

Tiêu đề chính của đoạn văn là gì?

A. Lịch sử của đèn nháy (đèn ﬂash)

B. Các học thuyết về cách mà mắt phản ứng lại ánh sáng

C. Công nghệ chụp ảnh hiện đại

D. Những nguy hiểm của việc sử dụng đèn ﬂash thủa ban đầu

Căn cứ vào các thông tin ở cả đoạn 1 và 2:

- “Photoﬂash is now generated electronically, but the earliest form, first used in 1864, was a paper bag containing magnesium wire and some oxygen-rich substance, such as potassium chlorate." (Đèn flash ngày nay được tạo ra hàng công nghệ tự động hóa, nhưng thủa sơ khai, khi lần đầu tiên được sử dụng vào năm 1864, nó chỉ là một túi giấy có chứa dây dẫn magiê và một số chất giàu oxy, như kali clorat.)

- “The evolution of the photoﬂash was slow, ﬂashbulbs, containing fine wire made of a metal, such as magnesium or aluminum, capable of being ignited in an atmosphere of pure oxygen at low pressure, were introduced only in the 1920's." (Sự phát triển của đèn flash diễn ra chậm, các bóng đèn nháy, chứa dây dẫn làm bằng kim loại, như magiê hoặc nhóm, có khả năng bị đốt cháy trong môi trường chứa oxy tinh khiết ở áp suất thấp, chỉ được phát minh vào những năm 1920.)

Như vậy có thể thấy xuyên suốt bài đọc là lịch sử ra đời và phát triển của đèn ﬂash => Do do, đáp án là A
