Logical reasoning consists of two (2) sub-tests, as follows: 1) Verbal Reasoning; and 2) Non-Verbal Reasoning. Power Test, on the other hand, have four (4) sub-tests, namely: 1) English; 2) Science; 3) Mathematics; and 4) Mechanical Technical. The Science sub-test consists of the following subject areas: 1) Biology; 2) Chemistry; 3) Physics; and 4) Earth Science. Verbal Reasoning tests your ability to understand, analyze and interpret information. It also measures your ability to extract meaning from complex information and to think logically and analytically. Non-Verbal Reasoning measures your abilities to: visualize and transform images in your mind; recreate visual experiences and reasoning about shape, measurement, depiction and navigation; and mentally rotate and manipulate two and three-dimensional spaces. The English sub-test measures your ability to apply the rules of the English language, specifically on grammar and syntax, vocabulary and reading comprehension. Science sub-test consists of test items in Biology, Chemistry, Physics, and Earth Science that will test your ability to accomplish various important scientific tasks. Mathematics sub-test will measure your ability to comprehend qualitative relationships and their representations. Mechanical-Technical will measure your ability to acquire information about everyday physics and to comprehend mechanical relationships. It consists of mechanical and electrical problems, as well as items that deal with physical forces. The answer key is given at the end for your reference. Some answers are provided with rationalization, or an explanation as to how the answers were arrived at, for your guidance.

Renewable energy is more cost-efficient and environment-friendly than fossil fuels. The process of generating it relies on wind, sun, water, and organic matter. 2Since these energy sources are abundant and easily replenished, the cost of electricity is not too expensive. 3In contrast, fossil fuels depend on limited resources that may eventually deplete, thus the cost of electricity can considerably increase. 4Electricity generated from renewable sources is also more beneficial to nature. 5Technologies that produce renewable energy have minimal emissions that harm the atmosphere, while coal-fired power plants release harmful emissions that contribute to global warming. What pattern of paragraph development is evident in the passage? A. cause-effect B. problem-solution C. definition by example D. comparison-contrast 12. Same text as item #11 (Renewable energy).

Article: “Mobile Phones” The Philippines is known as the texting capital of the world. Filipinos send over 200 million texts daily, ten times the per capita world average. Texting allows Filipinos to express themselves in new ways. They text what they would not normally say in a face-to-face encounter. This has led to new ways of relating with others as well as opened areas of inner-subjective reflection. New and radical identities become possible. However, these technologies have also had less immediately beneficial consequences. Cell phone theft is now a major criminal problem in urban areas. Youth gambling has also become a major concern, given its close association with recreational texting. But civil society has also used it to organize political protests, aiding in the overthrow of President Estrada in January 2001. This capacity of CMICTs to mobilize people has also been reported for countries such as Venezuela during its current strife. CMICTs enable what are referred to as “smart mobs,” loosely organized groups capable of micro-coordinating their activities for specific purposes. Smart mobs differ from political demonstrations by the lack of a controlling center. Instead, they consist of loose networks, often P2P (person-to-person) linkages resulting in the close coordination of otherwise independent members. The model of center- periphery or a central hierarchy is replaced by multicentric nodes of mobilization. Each node is autonomous but capable of micro-coordinating its movements with other nodes for a specific and often single-issued end. Their relative autonomy allows for diverse nodal centers representing distinct interests to participate collectively. After such events, each node reverts to its original and individual condition.

They need no police to promulgate their peace because they tolerate each other’s smell or greed. Friends to dark and filth, they do not choose their meat.
