Read the following passage and answer the item that follows. Your answers to this item should be based on the passage only. Many farmers use synthetic pesticides to kill infesting insects. The consumption of pesticides in some of the developed countries is touching 3000 grams/hectare. Unfortunately, there are reports that these compounds possess inherent toxicities that endanger the health of the farm operators, consumers and the environment. Synthetic pesticides are generally persistent in environment. Entering in food chain they destroy the microbial diversity and cause ecological imbalance. Their indiscriminate use has resulted in development of resistance among insects to insecticides, upsetting of balance in nature and resources of treated populations. Natural pest control using the botanical pesticides is safer to the user and the environment because they break down into harmless compounds within hours or days in the presence of sunlight. Plants with pesticidal properties have been in nature for millions of years without any ill or adverse effects on the ecosystem. They are easily decomposed by many microbes common in most soils. They help in the maintenance of biological diversity of predators and human health hazards. Botanical pesticides formulated from plants are biodegradable and their use in crop protection is a practical sustainable alternative. On the basis of the above passage, the following assumptions have been made: 1. Synthetic pesticides should never be used in modern agriculture. 2. One of the aims of sustainable agriculture is to ensure minimal ecological imbalance. 3. Botanical pesticides are more effective as compared to synthetic pesticides. Which of the assumptions given above is/are correct?

The critical reasoning question is based on a short argument, a set of statements, or a plan of action. For each question, select the best answer of the choices given. Pesticides are used to control various pests and disease carriers such as rats, ticks and mice. They are used in agriculture to control weeds and fungi too. A pesticide is a chemical or biological agent that kills pests. Although pesticides have benefits, some have drawbacks too if they are used in larger quantities. Given below are some options, select the one which is not one of the the advantages of pesticides.
Consider the following statements and choose the correct answer:
1. The process of soil formation is so slow that soil may be considered as a non-renewable resource
2. Soil pollution may be the direct effect of dumping and disposal of wastes, application of agrochemicals or the indirect result of air pollution
3. Pesticides increase the population and number of species of living organisms which facilitate the structure and fertility of the soil
4. Several pesticides or their degradations are absorbed by the plants
A small and medium enterprise imports two components A and B from Taiwan and China respectively and assembles them with other components to form a toy. Components A contributes to 10% of production cost while components B contributes to 20% of production cost. Usually the company sells this toy at 20% above the production cost. Due to increase in the raw material and labour cost in both the countries ,component A became 20% costlier and components B became 40% costlier. Owing to these reasons the company increased its selling price by 15%. Considering that cost of other components does not change. What will be the profit percentage if the toy is sold at the new price?
