A.I. Explanation:

Option 1: "Always translate from a second language into your native language"

Explanation: This option is incorrect because the text does not mention the specific guideline of translating only from a second language into one's native language. The speaker emphasizes being choosy about commissions and consulting resources when unsure, but does not specify a preference for translation direction.

Option 2: "Ask a native speaker if you are not sure of the meaning of something"

Explanation: This option is correct as the text advises that if you have any doubt about the meaning of something, you should consult a dictionary or someone whose mother tongue is the language you are translating from. This aligns with the idea of seeking help from a native speaker to ensure accuracy.

Option 3: "Take care to choose the right meaning of a word if you use a dictionary"

Explanation: This option is incorrect because while the text mentions consulting a dictionary, it does not specifically advise on the importance of choosing the right meaning of a word. The focus is more on the necessity of checking meanings when in doubt rather than the process of selecting meanings from a dictionary.

Option 4: "Don’t translate technical texts unless you are familiar with the subject"

Explanation: This option is correct as the speaker explicitly states that it is not advisable to accept jobs on topics you are not knowledgeable about, especially in fields like medical or legal translation, which could lead to serious errors. This directly supports the idea of avoiding technical texts without proper familiarity.

Option 5: "Ask what your translation will be used for"

Explanation: This option is incorrect because the text does not mention the importance of asking about the intended use of the translation. The speaker focuses on the need for knowledge and consulting resources rather than inquiring about the purpose of the translation.
