Alluvial Soils : These soils are formed by the deposition of sediments brought by rivers. They are rich in humus and very fertile. They are found in Great Northern plain, lower valleys of Narmada and Tapti and Northern Gujarat. These soils are renewed every year.
Black Soils: These soils are made up of volcanic rocks and lava-flow. It is concentrated in the parts of Maharashtra, Chhattisgarh, Madhya Pradesh, Gujarat, Andhra Pradesh and Tamil Nadu. It consists of Lime, Iron, Magnesium and also Potash.
Red Soils: These are formed by weathering of ancient metamorphic rocks of Deccan Plateau. Due to iron composition these soils are red in color. When iron content is lower it is yellow or brown. They cover the parts of Tamil Nadu, Andhra Pradesh, Chhattisgarh, Karnataka, Maharashtra and Orissa.

Op is also short for operation, when referring to a calculation performed by a CPU. For instance a "no-op" is a special CPU operation that does nothing, and a "flop" is a floating-point mathematical operation.

Read the passages given below and answer any 10 questions that follow them: January 26 is celebrated as Republic Day in our country. It was on this day, in 1950, the new constitution of independent India came into force and India became a democratic republic. The Constituent Assembly headed by Dr. Rajendra Prasad, with Dr. B.R. Ambedkar as the Chairman of the Drafting Committee, took more than two years to bring the world’s lengthiest constitution to its final shape. The enormous task before the Constituent Assembly was to frame the basic law that would formalize India as a truly democratic nation. Democracy is aptly defined as a system of Government by the people, for the people and of the people. The founding fathers of the Constitution, therefore, had to ensure that the basic law of the land contained sufficient provisions for the fulfilment of the democratic aspirations of the people of India not only in the political sphere but also in the social and economic spheres. That explains the inclusion of a separate part in the Constitution, called the Directive Principles of State Policy. These principles signify the fact that the framers of the Constitution were well aware of the wide gaps and inequalities that existed among the various sections of the Indian population. The Constitution makers had the wisdom to appreciate that political democracy is meaningless when an overwhelming majority of the population is historically trapped in poverty, illiteracy, ill-health and superstition. The Central and State Governments were expected to frame policies so that every citizen is assured of a decent living standard irrespective of ***, caste, religion, language and region. The makers of our Constitution describe India as a Union of States and not as a federation. Being well conversant with the diversity of the nation in terms of the language, religion, caste and region, and its implications on the intended socio-economic development of the country as a whole, the makers of the Constitution opted for a political system in which the Central Government is equipped with overwhelming administrative, legislative and financial muscle. Most of the nations’ policies and programmes for socio-economic development originate at the Central Government, and the responsibility for their successful implementation is entrusted to the states. The programmes for the socio-economic development originate at state level regional level district level central government level The British had left behind a developed India a wealthy India a poverty-stricken, illiterate India a strong and healthy India The constitution-makers describe India as a ________. Union of states Union of nations Union of territories Union of districts The constitution-makers took more than two years to bring the world’s ________ constitution to its final shape. simplest lengthiest heaviest shortest Find the word from the passage which means the same as recognizing the good quality of somebody. overlook appreciate disparage condemn Who is the Chairman of the Drafting Committee?

Modern technology has infiltrated the education sector and as a result, many college students now prefer taking online classes, as opposed to attending the traditional regular classes. This is because online classes are convenient for such students, and more so for those who have to both work and attend classes.

As such, online learning gives them the flexibility that they needed. In addition, online learning also gives an opportunity to students and professionals who would not have otherwise gone back to school to get the necessary qualifications. However, students who have enrolled for online learning do not benefit from the one-on-one interaction with their peers and teachers. The essay shall endeavor to examine the differences between online classes and the traditional classes, with a preference for the later.

Online classes mainly take place through the internet. As such, online classes lack the regular student teacher interaction that is common with traditional learning. On the other hand, learning in traditional classes involves direct interaction between the student and the instructors (Donovan, Mader and Shinsky 286).

This is beneficial to both the leaner and the instructors because both can be bale to establish a bond. In addition, student attending the traditional classroom often have to adhere to strict guidelines that have been established by the learning institution. As such, students have to adhere to the established time schedules. On the other hand, students attending online classes can learn at their own time and pace.

One advantage of the traditional classes over online classes is that students who are not disciplined enough may not be able to sail through successfully because there is nobody to push them around. With traditional classes however, there are rules to put them in check. As such, students attending traditional classes are more likely to be committed to their education (Donovan et al 286).

Another advantage of the traditional classes is all the doubts that students might be having regarding a given course content can be cleared by the instructor on the spot, unlike online learning whereby such explanations might not be as coherent as the student would have wished.

With the traditional classes, students are rarely provided with the course materials by their instructors, and they are therefore expected to take their own notes. This is important because they are likely to preserve such note and use them later on in their studies. In contrast, online students are provided with course materials in the form of video or audio texts (Sorenson and Johnson 116).

They can also download such course materials online. Such learning materials can be deleted or lost easily compared with handwritten class notes, and this is a risk. Although the basic requirements for a student attending online classes are comparatively les in comparison to students attending traditional classes, nonetheless, it is important to note that online students are also expected to be internet savvy because all learning takes place online.

This would be a disadvantage for the regular student; only that internet savvy is not a requirement. Students undertaking online learning are likely to be withdrawn because they hardly interact one-on-one with their fellow online students or even their instructors. The only form of interaction is online. As such, it becomes hard for them to develop a special bond with other students and instructors. With traditional learning however, students have the freedom to interact freely and this helps to strengthen their existing bond.

Online learning is convenient and has less basic requirements compared with traditional learning. It also allows learners who would have ordinarily not gone back to school to access an education. However, online students do not benefit from a close interaction with their peers and instructors as do their regular counterparts. Also, regular students can engage their instructors more easily and relatively faster in case they want to have certain sections of the course explained, unlike online students.
