Key Points

• "en-" is the correct prefix because it is used to form verbs that mean "to cause to be" or "to make." In this context, "enables" means to make it possible for cockroaches to sense their surroundings.
• The verb "enable" comes from the prefix "en-" and means "to give the ability to," which fits the context of the sentence about the antennas allowing cockroaches to sense their surroundings.
• Options 1, 2, and 4 are incorrect because they do not convey the intended meaning of allowing or providing the ability in this context.

Additional Information

• Option 1: "dis-" is incorrect because "dis-" means "opposite of" or "remove," which does not fit in the context of enabling cockroaches to sense their surroundings.
• Option 2: "un-" is incorrect because "un-" generally means "not" or "opposite of," which does not convey the idea of making something possible, as needed in this sentence.
• Option 4: "in-" is incorrect because "in-" often means "not" or "into," which does not fit the context of enabling an ability.

The correct answer is '2' i.e. envy .

Key Points

• Prefix “en-” typically means "to cause to be" or "to put into or onto", and is used to form verbs from nouns or adjectives.
• Option 1: enlist – The prefix "en-" is used with "list" to mean "to enroll or sign up", especially in military service.
• Option 3: encourage – "en-" is used with "courage" to mean "to give courage". This is a typical use of the en- prefix.
• Option 4: enlighten – "en-" is used with "lighten" to mean "to give light or understanding". This again uses "en-" as a prefix.
• Option 2: envy – This word does not contain the prefix "en-". It is a standalone root word derived from the Latin *invidia* (meaning ill will or jealousy), and not formed by adding a prefix to a base word.

Correct sentence: “Envy” is not a word formed with the prefix “en-”; it is a root word by itself.

Additional Information

• Common words with “en-” prefix: enable, enlarge, empower, enrich, endanger – all use “en-” to express causation or transformation.

Key Points

• The prefix "un-" is often used to create the negative form of adjectives and verbs.
• When added to "clear," it forms "unclear," which is a commonly used word meaning not clear or ambiguous.
• The other options do not typically form standard English words with the prefix "un-".

Additional Information

• interpret: The negative form is usually "misinterpret." "Uninterpret" is not a standard English word.
• appear: The negative form is "disappear." "Unappear" is not a standard English word.
• motivate: The negative form is "demotivate." "Unmotivate" is not a standard English word.

The correct answer is: Option 1 i.e. "like".

Key Points

• The word "like" means to feel affection or regard for someone or something or to find it agreeable. (पसंद करना)
  • Example: I like listening to music during my free time.
• When the prefix 'dis' is added to "like," it forms the word "dislike", which means to feel aversion or distaste for something. (नापसंद करना)
  • Example: She dislikes eating spicy food.

Therefore, the correct answer is: Option 1.

Additional Information

Here are the other options explained along with their Hindi meanings and example sentences:

• Study (पढ़ाई करना): The act of learning or acquiring knowledge through reading, research, or practice.
  • Example: He studies history to understand the events of the past.
