Question: 1) What questions can be asked from the paragraph below. It could be any question related to this paragraph.

The news article published in the Journal of Molecular Diagnosis, presents two different studies which developed experimental research about the detection of cancer through blood tests. Those studies exposed how the cancer disease can be diagnosed by the identification of three mutation-bearing molecules.

The first study, conducted in California in Stanford University, a new form of blood procedure known as single colour digital PCR can detect DNA changes generated by cancer cells. The single colour digital PCR merely takes a few millilitres of blood, and it can be performed by a general physician and do not demand the use of a specialised lab.

In Netherlands, the VU University Medical center revealed that the RNA present in the bloodstream can help with the diagnosis of lung cancer. To do that, the researchers used the RNA present in platelets to detect the presence of tumor cells. This new technique was named as thromboSeq, and showed a great efficiency in the identification of lung cancer which can be used as a complementary test.

Cancer diagnostic can be very demanding, time consuming and expensive. There are scenarios that the patient is not even alive anymore when gets his specific diagnosis. Furthermore, some tests require larges amount of sample and very specialized staff during the whole process. The main advantage of the PCR and other molecular tests is because they are fast, sensitive and cheaper. Also, those techniques require less sample and allow a faster tracking of the disease. Thus, the PCR has an outstanding potential in the diagnosis and new applications of this method are released in a regular basis.

Question 2) What question can be asked or formed from this second paragraph?

When the popular literary artist, William Shakespeare coined the phrase, "varnish into thin air", it quickly became a cliché. Many people adopted it to express their desire to have all of their problems vanish into thin air, but little did we know that the same thin air will be the very place where scientists will discover solution to an important scientific problem. Amazingly, that became the irony of life when Elizabeth Clare of York University, while in the UK, coincidentally, embarked on a study intended to trap DNA out of the air in order to detect animals present in enclosures, similar to an experiment conducted simultaneously by another team of scientists in Copenhagen Zoo. After vacuuming DNA from the air, both teams used polymerase chain reaction (PCR), a technique that allows for multiplication of specific segments of DNA, to look at the DNA sequences. From there, they compared their discoveries against public databases for those animals.

Guess what? Both team of scientists succeeded!

Through this method, both teams detected several species of animals. This discovery will make for easy monitoring of wild animals in difficult-to-access places, such as caves and burrows. It will be useful in tracing missing land-dwelling animals in order to approach their local zoos for help. Prior to their research, traditional wildlife surveys which monitored animals by sight, or indirectly through clues that they left behind, like fur, etc., were done. With that method, certain animals, including the small, fast and shy ones were often missed.
