A Robot Fish has been developed by National University of Singapore's researchers from the Department of Electrical & Computer Engineering.This robot fish has movements which have been inspired by the movements of the carp . There are various purposes that it can be used for.It can help in underwater archaeology (  ).For example, it can enter a sunken city where human divers cannot enter.Just like a fish , it can also look at all the comers of particular wreckage.This robot can also be used for general purposes such as detection of leakages in a pipeline or for laying down communication cables across oceans.It also has possible military uses. In order to copy carp movements, Mr.Fan studied the movements of the fish for around 3 months.He studied all the different movements of carp using different cameras and then converted these movements mathematically to transfer this data to the robot using many actuators . Professor Xu commented on the robot that the current models that copy fish movements are capable only of 2D movements which limits their capability as they are not able to dive into water.He said that his model is the first model with 3D movements which allows it to dive as well as float with the help of its fins, just as a normal fish would do.Hence, this fish model robot has much greater movement capability.It would be much harder for enemies to detect as compared to traditional ones when used for military purposes. The researches want to make their robot fish even smaller, more realistic while adding more sensors such as GPS and video camera to it.This will improve its autonomous 3D movement.They are also planning to test the fish by giving it more difficult tasks such as detecting various objects. Which of the following would be the best title for the text? A) First Robot Fish with Autonomous 3D Movement used widely B) First Robot Fish with Autonomous 3D Movement treading the ocean C) First Robot Fish with Autonomous 3D Movement created in Singapore D) First Robot Fish with Autonomous 3D Movement's general purposes

Imagine that the genome   is a book.The book consists of 23 chapters with thousands of stories made up of paragraphs, words and letters on different levels.There are one billion words in the book, as long as 800 Bibles; if I read the genome out to you at the rate of one word per second for eight hours a day, it would take me centuries; if I wrote out the human genome, one letter per millimeter, my text would be as long as the River Danube.This is a huge volume, a book of great length, but it all fits inside an extremely small cell nuclear  that fits easily upon the head of a pin. The idea of the genome as a book is not, strictly speaking, even a metaphor.It is true to a great extent.A book is a piece of digital information, written in one-directional form and defined by a code that translates a small alphabet of signs into a large dictionary of meanings through the order of their groupings.So is a genome.The only difference is that all English books read from left to right, while some parts of the genome read from left to right while some from right to left, but never both at the same time. While English books are written in words of different lengthens using twenty-six letters, genomes are written entirely in words of three-letter length, using only four letters, and instead of being written on flat pages, they are written on long chains of DNA molecules  . The genome is a very clever book, because in the right condition it can both photocopy itself and read itself. It can be concluded that the passage is mainly written for   _  . A) specialists in the field B) general readers C) natural scientists D) readers with professional knowledge
