$1)$ The question assumes that the most important features when buying a new television are limited to price and brand, potentially overlooking other important features like screen size or resolution.

$2)$ The question lacks specific frequency options, making it difficult for respondents to provide an accurate answer. It would be better with defined options like "Never," "Rarely," "Occasionally," "Frequently," etc.

$3)$ The wording of the question might be seen as overly formal or technical, potentially leading to confusion. Using more common terms like "headache" instead of "cephalgia" would improve clarity.

$4)$ The question is unclear about the significance of buying more than one loaf of bread at a time. It could be improved by specifying the purpose or context, such as storage habits or consumption patterns.

$5)$ The question assumes that consumers intend to buy a new car and visit dealers. A more inclusive version could ask about their general approach to purchasing decisions, allowing for a wider range of responses.
