Choose the best answer in the choices: TRUE OR FALSE

a. Statement I is true and Statement II is false

b. Statement I is false and Statement II is true

c. Both statements are true

d. Both statements are false

1. Statement 1: Air pollutant is a known substances in the air that can cause harm to humans and the environment. Statement 2: Materials engineers develop facilities and methods to capture and store water from storms while avoiding and/or minimizing flooding.

2. Statement 1: Maharlika Highway is the Longest Highway at 3,571 km, that consist of roads, bridges and ferry services. Statement 2: Kennon Road is the oldest road to Baguio, formerly known as Baguio road.

3. Statement 1: N1 to N10 are main routes or priority corridors connecting three or more cities while N11 to N82 roads are linking two cities. Statement 2: Road transportation network consists of a system of interconnected ways designed to carry traffic and generally forms the most basic level of transport infrastructure in an urban area.

4. Statement 1: The HEIGHT OF SIGNS mounted approximately at right angles to the direction, and facing the traffic and generally placed on the left side of the roadway. Statement 2: The ILLUMINATION & REFLECTORIZATION, intended to convey messages during both daytime and night time. At night time, achieved through illumination or by using reflective materials for signs.

5. Statement 1: The more vehicles that are on a roadway the lesser congested it is, and usually it leads to stopped or stop-and-go movement. Statement 2: Engineers like to describe congestion as an excess of vehicles on all of the portion of roadway at a particular time resulting in speeds that are slower than normal.

6. Statement 1: Barrages are diversion structures which help to divert a portion of the stream and river for meeting demands for irrigation or hydropower. They also help to increase the level of the water slightly which may be advantageous from the point of view of increasing navigability or to provide a pond from where water may be drawn to meet domestic or industrial water demand. Statement 2: The development of water resources potential should be such that in doing so there should be any degradation in the quality or quantity of the resources available at present. Thus the development should be sustainable for future.

7. Statement 1: Ground water contamination occurs due to human interference and also natural factors. To promote human health, there is urgent need to prevent contamination of ground water and also promote and develop cost-effective techniques for purifying contaminated ground water for use in rural areas like solar stills. Statement 2: Contamination of ground water due to over-exploitation has also emerged as a serious problem. It is difficult to restore ground water quality once the aquifer is contaminated.

8. Statement 1: Phase of transportation engineering that deals with planning, geometric design and traffic operations of roads, streets, and highways and their networks, terminals and relationships with other modes of transportation. Statement 2: For PNP-RTMO’s, a personnel is dispatched on strategic choke points and major thoroughfares to conduct traffic direction and control to ensure the smooth flow of traffic.

9. Statement 1: Commonwealth Act 146 (Public Service Act of 2003)- Gives the LTFRB power to compel any public service provider to furnish safe, adequate, and proper service as regards the manner of furnishing the same as well as the maintenance of necessary materials and equipment.
