Focusing on plastic pollution, the June issue of the National Geographic magazine created quite a buzz on social media, contrary to expectations after the cover featured a plastic bag submerged in an ocean with a ’Planet or Plastic?’ text on it. Ironically, the magazine itself was wrapped in a double layer of plastic. Which of the following options can be the reason for the magazine to go viral on the internet as inferred from the statements? I. It highlighted the amount of single-use plastic that enters in the world’s oceans which is a major environmental concern these days. II. National Geographic kicked off its ‘Planet or Plastic’ campaign, the magazine’s multiyear effort to raise awareness about the global plastic trash crisis through the cover. III. The magazine about ocean plastic pollution came wrapped in a plastic bag inside another plastic bag. IV. Because they realized the major flaw and announced that the magazine will no longer be shipped to readers in a plastic bag but will be sent out in a paper envelope instead.
Consider the following statements: 1. When a soil sample is dried beyond its shrinkage limit, the volume of the soil slowly decrease 2. The plastic limit is always lower than the liquid limit for any type of soil 3. At the liquid limit, the soil behaves like a liquid and possesses no shear strength at all 4. When subjected to drying, the volume of the soil remains unchanged once the water content of the soil goes below its shrinkage limit Which of the above statements are correct? 
When the plastic limit of a soil is greater than the liquid limit, then the plasticity index is reported as:
When the Liquid limit of a soil is less than the plastic limit, then the plasticity index is reported as 
The soil was tested in a National research center and its liquid limit was found to be 15% and the plasticity index was found to be 3%. According to Cassagrande's plasticity chart, which soil type is this?
A fine grained soil has liquid limit of 60 and plastic limit of 20 as per plasticity chart. According to IS classification, the soil is represented by which of the following letter symbols?
In the following question, the first and the last part of the sentence/passage are numbered 1 and 6. The rest of the sentence/passage is split into four parts and named P, Q, R, S. These four parts are not given in their proper order. Read the sentence/passage and find out which of the four combinations is correct. S1. Plastic bags are a major cause of environmental pollution. P. Many countries around the globe have either ban the plastic bag or Levi tax on it. Q. Plastic as a substance is non-biodegradable and thus plastic bags remain in the environment for hundreds of years polluting it immensely. R. However, the problem hasn’t been solved completely because the implementation of these measures hasn’t been as successful. S. It has become very essential to ban plastic bags before they ruin our planet completely. S6. Research shows that waste plastic bags have been a major reason for untimely animal deaths.
Consider the following statements: 1. Illite is the mineral largely responsible for the swelling and shrinkage behaviour of clayey soils. 2. A differential free swell value of 55% indicates a soil with low degree of expansiveness. 3. Higher the plasticity index of a soil, greater its swelling potential. 4. A low shrinkage limit of a soil indicates possibility of swelling at low water content. Which of the above statements are correct?
There are six friends who have different height and they stand according to their height information as given below. Q is greater than P and S. M is greater than P. T is greater than P who is greater than O. M is greater than Q. T is smaller than Q. Who among the following is the smallest in height?
Read the paragraph and answer the question that follows: Incessant combustion of fossil fuels emits toxic gases, polluting the air; urbanization results in deforestation and hence poor air quality; littering of plastic waste damages the productivity of soil and pollutes water bodies. Environmental pollution results in more serious consequences like – global warming, unexpected climatic changes, depletion of natural resources, species depletion, and various other adverse effects leading to a lowered sustainability of life on earth. Another prime contributor to the pollution of the environment is plastic pollution. Plastic bags those are not disposed of properly, reach the soil and water bodies, polluting them and damaging dependent lives. Being non-bio degradable plastic lingers around for years, rendering them useless. What is the prime contributor to pollution?
