A type of intelligence test in which the difficulty level of questions gradually increases and the time factor is secondary :

Question

Accepted Answer

Option 2, Power Test, is the correct answer because a power test is specifically designed to measure an individual's maximum ability or potential. The questions in a power test are arranged in increasing order of difficulty, starting with relatively easy questions and gradually progressing to very challenging ones. The emphasis is on the examinee's ability to solve difficult problems, and time limits are usually generous or even non-existent, making the time factor secondary. The goal is to assess the depth of knowledge and problem-solving skills, not how quickly someone can answer questions.

Here's why the other options are incorrect:

*   **Option 1: Verbal Test:** Verbal tests assess comprehension and reasoning using language-based questions. While difficulty can vary, the primary focus is on verbal skills, not necessarily a progressively increasing difficulty level to assess maximum potential. Time may or may not be a significant factor, depending on the specific verbal test.

*   **Option 3: Speed Test:** Speed tests are designed to measure how quickly an individual can answer a large number of relatively easy questions within a strict time limit. The difficulty level of the questions is generally low and consistent. The emphasis is on speed and accuracy under pressure, not on tackling increasingly difficult problems.

*   **Option 4: Performance Test:** Performance tests assess practical skills and abilities through hands-on tasks or activities, rather than written or verbal questions. While performance tasks can vary in complexity, the defining characteristic is the use of physical manipulation or demonstration of a skill, not a progressively increasing difficulty level of questions in a traditional test format.
