L1 habits interfere and hinder the learner in learning the forms of L2.

• A. Interference
• B. Variation
• C. Omission
• D. Simplification

Answer: (A)

Interference happens when habits from a learner’s first language shape how they use the second language, often hindering the correct formation of L2 forms. This captures the idea that L1 patterns can transfer into L2, leading to errors as learners try to apply familiar rules to English. For instance, a learner might carry over word order or omit articles because those features function differently in their L1. That makes this option the best fit because it directly describes the transfer from L1 that can hinder learning L2 forms. Variation refers to different ways language is used in context, not to transfer from L1; omission describes leaving out elements, and simplification describes reducing complexity—neither of these specifically accounts for the influence of L1 habits on L2 forms.
