Solution

The word ‘persistently’ means ‘ happening repeatedly or for a long time, or difficult to get rid of.’ Lean and mean- using only what is necessary, and determined to work effectively in order to compete successfully. Vested interests- a strong personal interest in something because you could get an advantage from it. Retrogression- the act of returning to an older and worse state. These telemarketers have been calling me persistently , even though I said I was not interested in their product.
