Explanation

Rationalism is a metaphysical system that emphasizes reason as the primary source of knowledge.

It contrasts with empiricism, which relies on sensory experience and faith-based knowledge systems.

Explanation

The sentence has one independent clause: "Neither Salma nor Aisha ate dinner after a long day at work."

There are no dependent clauses or coordinating conjunctions linking multiple independent clauses, so it is a simple sentence despite having a compound subject.

Explanation

Every real number is either a rational or irrational number: True. A real number can either be expressed as a fraction (rational) or cannot (irrational).

Every whole number is a natural number: False. Whole numbers include 0, but natural numbers start from 1. Therefore, 0 is a whole number but not a natural number.

All natural numbers are integers: True. Natural numbers are a subset of integers.

All integers are rational numbers: True. Every integer can be written as a fraction (e.g., 

5 = 5/1), so all integers are rational.

Explanation

British empiricists like Thomas Hobbes believed that knowledge comes from sensory experience, not from innate ideas or authority.

Hobbes famously stated that "man is a wolf to another man" and believed that all men act in self-interest, hence "every man should be held a knave."

Explanation

These tools helped astronauts drill into the lunar surface and bring back samples without power cords, making them more practical in space.

Explanation

Explanation

BTES stand for Beginning Tender Evaluation Study.

The BTES suggests that acquiring knowledge is best viewed as an ongoing process over multiple years.

It emphasizes that learning doesn't happen instantly but develops progressively over time.

Explanation

Let's denote the son's current age as x. Then the father's current age is 13x.

After 4 years:

Son's age = x + 4

Father's age = 13x + 4

According to the problem, after 4 years, the father's age will be 5 times the son's age:

13x + 4 = 5(x + 4)

13x + 4 = 5x + 20

8x = 16

x = 2

So, the father's current age is 13x = 13 * 2 = 26.

Explanation
