Answer Key:
- have influenced — The present perfect simple is used here because it indicates a completed action relevant to the present situation.
- have become — The present perfect simple is appropriate as it refers to a change that has relevance to the current state of skepticism.
- has been changing — The present perfect continuous form emphasizes the ongoing nature of the change.
- has been — The correct form is "has been" because "cults" is plural, so the verb should be "have been."
- are, have influenced, has increased — The first sentence uses the present simple for a current state, the second uses the present perfect simple for a completed action relevant to the present, and the last uses the present perfect simple to indicate a change over time.
Grammar Point: Reported Statements (Tense Backshift)
Why this point appears in the article: The article includes direct quotes and statements made by Hortensia Valcárcel, which can be transformed into reported speech, illustrating the need for tense backshift.

Answer Key:
- hid — The past tense is used here because it reflects the backshift in reported speech.
- would be — The future tense "will be" shifts to "would be" in reported speech.
- could manipulate — The modal verb "can" shifts to "could" in reported speech.
- was more skeptical — The present tense "are" should be changed to "were" to reflect the past tense in reported speech.
- a) — The correct reported form requires a shift to the past tense, so "shared" is correct.
Grammar Point: Zero/First Conditional
Why this point appears in the article: The article discusses potential outcomes and general truths about cults and social media, which can be expressed using zero and first conditional structures.
What learners need to understand: The zero conditional is used for general truths or facts (if + present simple, present simple), while the first conditional is used for real and possible situations in the future (if + present simple, will + base verb). Common errors include mixing the two forms or using incorrect verb tenses.
