Meaning: 'Selective' means choosing carefully or intentionally, particularly in the context of breeding where specific traits are desired.

Wrong options:

• particular: 'Particular' refers to something specific but does not convey the intentionality of choice in breeding, making it less suitable here.
• planned: 'Planned' suggests a premeditated approach but lacks the nuance of choosing specific traits, which is central to the concept of breeding.
• featured: 'Featured' implies prominence or display, which does not relate to the concept of breeding practices and is therefore irrelevant.

Correct answer: pathologies

Explanation: The word 'pathologies' is appropriate as it refers to diseases or disorders, which aligns with the context of distortions in body shape that are viewed negatively in humans. This fits both grammatically and contextually within the sentence.

Meaning: 'Pathologies' refers to the study of diseases or the conditions of diseases, particularly in a medical context.

Wrong options:

• biologies: 'Biologies' refers to the study of living organisms and does not fit the context of discussing distortions as diseases.
• pschycologies: 'Pschycologies' appears to be a misspelling of 'psychologies,' which relates to the mind and behavior, not physical conditions or distortions.
• greek: 'Greek' refers to a nationality or language and is completely unrelated to the context of discussing physical distortions.

Correct answer: litter

Explanation: The term 'litter' is the correct choice as it refers to a group of offspring born at the same time, which is relevant to dog breeding. It fits grammatically and contextually, indicating the number of puppies produced in a single birth.

Meaning: 'Litter' means a group of young animals born to an animal at one time, particularly in the context of dogs.

Wrong options:

• waste: 'Waste' refers to something discarded or not useful, which does not relate to the context of breeding and offspring.
• removal: 'Removal' implies taking something away, which does not fit the context of discussing the size of offspring.
• structure: 'Structure' refers to the arrangement or organization of something, which is not relevant to the context of breeding and offspring.

Correct answer: Moreover

Explanation: The word 'Moreover' is suitable as it serves as a discourse marker that adds information, indicating that the following statement builds on the previous one. It fits grammatically and contextually, enhancing the flow of ideas.

Meaning: 'Moreover' means 'in addition' or 'furthermore,' used to introduce an additional point that supports the previous statement.

Wrong options:

• However: 'However' indicates a contrast or exception, which does not align with the context of adding information.
• Nevertheless: 'Nevertheless' also suggests a contrast, which is not appropriate here as the sentence continues to build on the previous idea.
• As soon as: 'As soon as' indicates a time-related condition, which does not fit the context of adding information.

Correct answer: ideal

Explanation: The term 'ideal' fits well as it describes something that is perfect or most suitable for a particular purpose, which in this case refers to the experimental animal for genetic studies. It aligns grammatically and contextually with the sentence.

Meaning: 'Ideal' means the best or most suitable option for a specific purpose or situation.

Wrong options:

• last: 'Last' implies finality or the end of a sequence, which does not relate to the suitability of an experimental animal.
• great: 'Great' suggests something of high quality but lacks the specificity of being the most suitable for experimental purposes.
• basic: 'Basic' implies something simple or fundamental, which does not convey the notion of being the best choice for genetic research.
