To fact-check the statements:

1. To determine whether some hearing losses experienced by middle-aged adults are due to exposure to noise, you can consult research studies and medical literature on the topic. These sources can provide data and evidence on the relationship between noise exposure and hearing loss.

2. To verify whether a combination of progesterone and estrogen (HRT) is commonly used to treat immune system disorders, you can consult medical literature and professional medical organizations' guidelines. These sources will provide information on the recommended uses and effectiveness of HRT.

3. To confirm whether men experience the same sudden downward shift in reproductive ability as women, and if it is called climacteric, you can consult reputable sources such as medical textbooks or research papers. These sources can provide information on the specific physiological changes that occur in men and the associated terminology.

4. To determine the trends in the incidence of smoking worldwide and in North America, you can consult global and regional statistics on smoking rates. These statistics are often collected and published by organizations such as the World Health Organization (WHO) or national health agencies.

5. To assess the safety of talking on a cell phone while driving and whether the brain attends to what is being said rather than what is being seen, you can refer to scientific studies on distracted driving and cognitive processes. These studies can provide insight into the effects of multitasking on attention and driving performance.

6. To verify whether Spearman proposed that intelligence is a single entity called "g," you can consult the original works of Charles Spearman and subsequent literature discussing his theories. These sources will explain Spearman's concept of general intelligence and how it relates to his overall theory of intelligence.

7. To determine whether both fluid and crystallized intelligence increase with age for most people, you can consult longitudinal studies and research on intelligence and aging. These studies can provide data on the patterns of cognitive development throughout adulthood.

8. To confirm whether developmentalists use the term "expert" only for people who are extraordinarily gifted in a particular test, you can review the literature on expertise and expert performance in various domains. This research will provide insights into the criteria and definitions used to classify individuals as experts.

9. To assess whether experts often cannot explain how they come to particular conclusions in their area of expertise, you can refer to studies and discussions on expert decision-making and intuition. These sources can offer insights into the cognitive processes and tacit knowledge that experts utilize.

10. To determine whether novices tend to be better than experts at developing strategies to accomplish a particular test, you can consult studies on expertise development and problem-solving. These studies may explore the differences in approach and performance between novices and experts in various domains.

11. To verify whether, by late middle age, a person typically gains weight and loses nearly an inch in height, you can consult research on physical changes during aging. Studies on body composition and height changes over the lifespan can provide information on common trends observed in late middle age.
