It is perhaps not surprising that debate has arisen over bioluminescence-based biotechnologies because although they may lead to remarkable products, the biological process in the creatures that serve as models for biomimetic products are themselves not entirely understood. To take a single example, green fluorescent protein (GFP) extracted from certain species of jellyfish-Aequorea victoria, to be specific-and placed on a silicon dioxide substrate between two electrodes will organize itself into strands that absorb the photons from ultraviolet light and emit a detectable electric current. Researchers see great promise in this technology. For example, GFP strands could become a minute biophotovoltaic power pack from which could be created more cost-effective solar cells.
Despite the excitement over this promising research, questions about sustainability and method persist. The Aequorea victoria which exists in colonies in Puget Sound and from which GFP is derived-has been found in declining numbers over the last two decades. However, whereas the jellyfish were abundantly available for collection two decades ago, their numbers have now decreased. This decrease is not clearly related to collection, but it cannot be ruled out as a factor, as some research suggests that ocean conditions are generally favorable toward jellyfish overpopulation. Research into the application of GFP often yields inconsistent results because the jellyfish's bioluminescent activity is still not completely understood. The glowing effect, which appears only on a specimen's margins, is not continuous, and what provokes it is not known. Researchers in lab conditions can easily cause the bioluminescent reaction to occur, but when undisturbed, specimens rarely glow.

1. The author's primary purpose in this passage is to
A. discuss potential benefits of bioluminescence-based biotechnology and potential problems with its research.- The author does not simply asserts the problem and benefits of bioluminescence-based biotechnology. The author from the start sounds to tell the readers that the questions that have arised are not surprising.
B. discourage further research into Aequorea victoria's bioluminescent capabilities.- This is not the primary purpose of the passage
C. celebrate the promised benefits of biophotovoltaic production.- Celebrate--> NO
D. raise questions that need to be answered before research in bioluminescence-based biotechnologies can be sustainable or effective.- This is the primary purpose of the passage as the author highlights the problems and tells that these problems need to be fixed. This is the correct answerE. describe the beauty of the glow of bioluminescent jellyfish.- Out of scope
Question 2
2. The passage's discussion of biophotovoltaic power provides support for which of the following assertions?
A. The natural world is too fragile to endure the development of this technology.- This is a very extreme option; the passage's discussion does not support this.
B. The development of better solar cells is vital to renewable energy research.- This is not supported by the passage
C. The use of biophotovoltaic power may cause declining jellyfish populations in Puget Sound.- This is the best option choice as the author has mentioned that decline is population cannot be ruled out, so there are chances for it to happen. This is the correct answerD. A biological process might yield technological benefits even before it is fully understood.- This is not supported by the passage
E. Bioluminescence-based biotechnology will revolutionize the energy industry.- This is also an extreme answer option
Question 3
3. The first paragraph performs which of the following functions in the passage?
A. It lists problems associated with research into bioluminescent jellyfish in Puget Sound.- This is not the intent of 1st para
B. It gives an example of a controversial area of research and the benefits it may yield.- The 1st para is organised in this order. This is the correct answerC. It investigates the practicality of a potentially beneficial area of research and gives examples of problems that must be solved.- No investigation is carried here
D. It describes the technique used to cause extracted GFPs to emit electrical current.- Limited in scope
E. It encourages increased corporate and academic support of research into bioenergies.- Out of scope
