CAT Question of the Day Read the extract and answer the question that follows.
Much of the public forgets the gut when it comes to warding off the flu and other more threatening diseases, but the gut—and its army of beneficial bacteria—are essential in protecting us from harm. That's why eating genetically modified and/or conventionally farmed food could be a direct assault on your own health. Most recently, research has shown that Monsanto's herbicide, known as Roundup, is destroying gut health, threatening overall health of animals, people, and the planet significantly. The journal Current Microbiology recently published a study that caught Monsanto's Roundup herbicide's active ingredient, glyphosate, suppressing beneficial bacteria in poultry specimens. Given that gut health is directly linked to chronic illnesses and overall health, this isn't exactly welcome news for people who can't always afford or who lack access to organic, locally grown food. But it gets worse. While good bacteria died, highly pathogenic bacteria were unaffected by glyphosate. These pathogens include several strains of Salmonella and the class Colstridia, anaerobic bacteria known to be some of the deadliest known to us, including C. tetani (tetanus) and C. botulinum (botulin). According to the passage which of the following statements is/are true? - Glyphosate is the active element in the pesticides made by Monsanto.
- Genetically modified foods or conventionally farmed foods contain traces of glyphosate.
- Monsanto herbicide Roundup has been proved to cause chronic illnesses in human beings.
- Herbicides are primarily used to get rid of pathogenic bacteria.

Tip of the Day To see whether a number is prime or not one needs to check whether it is divisible by the prime numbers 2, 3, 5, 7 up to the prime number less than or equal to the square root of the number itself. For example, to check whether 997 is a prime number one needs to check its divisibility with the prime numbers 2, 3, 5, 7 .... to 31. Last year's Question of the day (26-May-12) If f is a function such that f(x + y) = f(xy) for all values of x, y ≥ 4. Domain of f is [8, ∞), and f(8) = 9, then find f(100).
