1. Where is a herniated lumbar disc most likely to cause pain?

Correct answer: C

Rationale: A herniated lumbar disc is most likely to cause pain along the sciatic nerve. The sciatic nerve is a long nerve that extends from the lower back down the back of each leg. Compression of the sciatic nerve by a herniated disc can lead to symptoms such as pain, numbness, tingling, or weakness that radiates down the leg. This condition is commonly referred to as sciatica. Choices A, B, and D are incorrect because a herniated lumbar disc typically affects the sciatic nerve, not the radial nerve, spinal cord, or tibial nerve.

2. As used in the second paragraph, what does the term ubiquitous mean?

Correct answer: C

Rationale: The correct answer is C: 'Found everywhere.' Ubiquitous in this context means widespread presence. In the provided extract, it is mentioned that MRSA bacteria have become ubiquitous not only in hospitals but also in various other settings, indicating they are found everywhere. Choice A, 'Indigenous,' is incorrect as it refers to something native or originating from a specific place, which is not the intended meaning in the context. Choice B, 'Often ignored,' is incorrect as ubiquitous means something that is widely present, not something that is ignored. Choice D, 'Dangerous,' is incorrect as ubiquitous does not directly imply danger, but rather the widespread presence of something.

3. What does Collusion refer to?

Correct answer: B

Rationale: Collusion refers to a secret agreement or conspiracy, often for deceitful or illegal purposes. While choices A, C, and D may involve some level of agreement or understanding, collusion specifically implies a secretive and usually dishonest arrangement, making choices A, C, and D incorrect in this context.

4. How many electrons are shared in a single covalent bond?

Correct answer: B

Rationale: The correct answer is B: '2'. In a single covalent bond, two electrons are shared between two atoms. Each atom contributes one electron to form the bond, resulting in the sharing of a total of two electrons. Choice A is incorrect because a single covalent bond involves the sharing of two electrons, not one. Choices C and D are incorrect as they do not represent the correct number of electrons shared in a single covalent bond.

5. Ratio and proportion 1.2:x=14:42.

Correct answer: D

Rationale: Cross-multiply to solve for 𝑥 x: 1.2 × 42 = 14 𝑥 1.2×42=14x 50.4 = 14 𝑥 50.4=14x 𝑥 = 50.4 14 = 3.6 x= 14 50.4 ​ =3.6
